SpringBoot3之Web编程

标签:Rest.拦截器.swagger.测试;

一、简介

基于web包的依赖,SpringBoot可以快速启动一个web容器,简化项目的开发;

web开发中又涉及如下几个功能点:

拦截器:可以让接口被访问之前,将请求拦截到,通过对请求的识别和校验,判断请求是否允许通过;

页面交互:对于服务端的开发来说,需要具备简单的页面开发能力,解决部分场景的需求;

Swagger接口:通过简单的配置,快速生成接口的描述,并且提供对接口的测试能力;

Junit测试:通过编写代码的方式对接口进行测试,从而完成对接口的检查和验证,并且可以不入侵原代码结构;

二、工程搭建

三、Web开发

1、接口开发

编写四个简单常规的接口,从对资源操作的角度,也就是常说的:增Post、删Delete、改Put、查Get,并且使用了swagger注解,可以快速生成接口文档;

@RestController
@Tag(name = "Rest接口")
public class RestWeb {
@Operation(summary = "Get接口")
@GetMapping("rest/get/{id}")
public String restGet(@PathVariable Integer id) {
return "OK:"+id;
}
@Operation(summary = "Post接口")
@PostMapping("/rest/post")
public String restPost(@RequestBody ParamBO param){
return "OK:"+param.getName();
}
@Operation(summary = "Put接口")
@PutMapping("/rest/put")
public String restPut(@RequestBody ParamBO param){
return "OK:"+param.getId();
}
@Operation(summary = "Delete接口")
@DeleteMapping("/rest/delete/{id}")
public String restDelete(@PathVariable Integer id){
return "OK:"+id;
}
}
@RestController
@Tag(name = "Rest接口")
public class RestWeb {

    @Operation(summary = "Get接口")
    @GetMapping("rest/get/{id}")
    public String restGet(@PathVariable Integer id) {
        return "OK:"+id;
    }

    @Operation(summary = "Post接口")
    @PostMapping("/rest/post")
    public String restPost(@RequestBody ParamBO param){
        return "OK:"+param.getName();
    }

    @Operation(summary = "Put接口")
    @PutMapping("/rest/put")
    public String restPut(@RequestBody ParamBO param){
        return "OK:"+param.getId();
    }

    @Operation(summary = "Delete接口")
    @DeleteMapping("/rest/delete/{id}")
    public String restDelete(@PathVariable Integer id){
        return "OK:"+id;
    }
}
@RestController @Tag(name = "Rest接口") public class RestWeb { @Operation(summary = "Get接口") @GetMapping("rest/get/{id}") public String restGet(@PathVariable Integer id) { return "OK:"+id; } @Operation(summary = "Post接口") @PostMapping("/rest/post") public String restPost(@RequestBody ParamBO param){ return "OK:"+param.getName(); } @Operation(summary = "Put接口") @PutMapping("/rest/put") public String restPut(@RequestBody ParamBO param){ return "OK:"+param.getId(); } @Operation(summary = "Delete接口") @DeleteMapping("/rest/delete/{id}") public String restDelete(@PathVariable Integer id){ return "OK:"+id; } }

2、页面交互

对于服务端开发来说,在部分场景下是需要进行简单的页面开发的,比如通过页面渲染再去生成文件,或者直接通过页面填充邮件内容等;

数据接口

@Controller
public class PageWeb {
@RequestMapping("/page/view")
public ModelAndView pageView (HttpServletRequest request){
ModelAndView modelAndView = new ModelAndView() ;
// 普通参数
modelAndView.addObject("name", "cicada");
modelAndView.addObject("time", "2023-07-12");
// 对象模型
modelAndView.addObject("page", new PageBO(7,"页面数据模型"));
// List集合
List<PageBO> pageList = new ArrayList<>() ;
pageList.add(new PageBO(1,"第一页"));
pageList.add(new PageBO(2,"第二页"));
modelAndView.addObject("pageList", pageList);
// Array数组
PageBO[] pageArr = new PageBO[]{new PageBO(6,"第六页"),new PageBO(7,"第七页")} ;
modelAndView.addObject("pageArr", pageArr);
modelAndView.setViewName("/page-view");
return modelAndView ;
}
}
@Controller
public class PageWeb {

    @RequestMapping("/page/view")
    public ModelAndView pageView (HttpServletRequest request){
        ModelAndView modelAndView = new ModelAndView() ;
        // 普通参数
        modelAndView.addObject("name", "cicada");
        modelAndView.addObject("time", "2023-07-12");
        // 对象模型
        modelAndView.addObject("page", new PageBO(7,"页面数据模型"));
        // List集合
        List<PageBO> pageList = new ArrayList<>() ;
        pageList.add(new PageBO(1,"第一页"));
        pageList.add(new PageBO(2,"第二页"));
        modelAndView.addObject("pageList", pageList);
        // Array数组
        PageBO[] pageArr = new PageBO[]{new PageBO(6,"第六页"),new PageBO(7,"第七页")} ;
        modelAndView.addObject("pageArr", pageArr);
        modelAndView.setViewName("/page-view");
        return modelAndView ;
    }
}
@Controller public class PageWeb { @RequestMapping("/page/view") public ModelAndView pageView (HttpServletRequest request){ ModelAndView modelAndView = new ModelAndView() ; // 普通参数 modelAndView.addObject("name", "cicada"); modelAndView.addObject("time", "2023-07-12"); // 对象模型 modelAndView.addObject("page", new PageBO(7,"页面数据模型")); // List集合 List<PageBO> pageList = new ArrayList<>() ; pageList.add(new PageBO(1,"第一页")); pageList.add(new PageBO(2,"第二页")); modelAndView.addObject("pageList", pageList); // Array数组 PageBO[] pageArr = new PageBO[]{new PageBO(6,"第六页"),new PageBO(7,"第七页")} ; modelAndView.addObject("pageArr", pageArr); modelAndView.setViewName("/page-view"); return modelAndView ; } }

页面解析:分别解析了普通参数,实体对象,集合容器,数组容器等几种数据模型;

<div style="text-align: center">

<h5>普通参数解析</h5>
姓名:<span th:text="${name}"></span>
时间:<span th:text="${time}"></span>

效果图展示

四、拦截器

1、拦截器定义

通过实现HandlerInterceptor接口,完成对两个拦截器的自定义,请求在访问服务时,必须通过两个拦截器的校验;

/**
* 拦截器一
*/
public class HeadInterceptor implements HandlerInterceptor {
private static final Logger log = LoggerFactory.getLogger(HeadInterceptor.class);
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response,
Object handler) throws Exception {
log.info("HeadInterceptor:preHandle");
Iterator<String> headNames = request.getHeaderNames().asIterator();
log.info("request-header");
while (headNames.hasNext()){
String headName = headNames.next();
String headValue = request.getHeader(headName);
System.out.println(headName+":"+headValue);
}
// 放开拦截
return true;
}
@Override
public void postHandle(HttpServletRequest request,HttpServletResponse response,
Object handler, ModelAndView modelAndView) throws Exception {
log.info("HeadInterceptor:postHandle");
}
@Override
public void afterCompletion(HttpServletRequest request,HttpServletResponse response,
Object handler, Exception e) throws Exception {
log.info("HeadInterceptor:afterCompletion");
}
}
/**
* 拦截器二
*/
public class BodyInterceptor implements HandlerInterceptor {
private static final Logger log = LoggerFactory.getLogger(BodyInterceptor.class);
@Override
public boolean preHandle(HttpServletRequest request,HttpServletResponse response,
Object handler) throws Exception {
log.info("BodyInterceptor:preHandle");
Iterator<String> paramNames = request.getParameterNames().asIterator();
log.info("request-param");
while (paramNames.hasNext()){
String paramName = paramNames.next();
String paramValue = request.getParameter(paramName);
System.out.println(paramName+":"+paramValue);
}
// 放开拦截
return true;
}
@Override
public void postHandle(HttpServletRequest request,HttpServletResponse response,
Object handler, ModelAndView modelAndView) throws Exception {
log.info("BodyInterceptor:postHandle");
}
@Override
public void afterCompletion(HttpServletRequest request,HttpServletResponse response,
Object handler, Exception e) throws Exception {
log.info("BodyInterceptor:afterCompletion");
}
}
/**
 * 拦截器一
 */
public class HeadInterceptor implements HandlerInterceptor {
    private static final Logger log  = LoggerFactory.getLogger(HeadInterceptor.class);
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response,
                             Object handler) throws Exception {
        log.info("HeadInterceptor:preHandle");
        Iterator<String> headNames = request.getHeaderNames().asIterator();
        log.info("request-header");
        while (headNames.hasNext()){
            String headName = headNames.next();
            String headValue = request.getHeader(headName);
            System.out.println(headName+":"+headValue);
        }
        // 放开拦截
        return true;
    }
    @Override
    public void postHandle(HttpServletRequest request,HttpServletResponse response,
                           Object handler, ModelAndView modelAndView) throws Exception {
        log.info("HeadInterceptor:postHandle");
    }
    @Override
    public void afterCompletion(HttpServletRequest request,HttpServletResponse response,
                                Object handler, Exception e) throws Exception {
        log.info("HeadInterceptor:afterCompletion");
    }
}

/**
 * 拦截器二
 */
public class BodyInterceptor implements HandlerInterceptor {
    private static final Logger log  = LoggerFactory.getLogger(BodyInterceptor.class);
    @Override
    public boolean preHandle(HttpServletRequest request,HttpServletResponse response,
                             Object handler) throws Exception {
        log.info("BodyInterceptor:preHandle");
        Iterator<String> paramNames = request.getParameterNames().asIterator();
        log.info("request-param");
        while (paramNames.hasNext()){
            String paramName = paramNames.next();
            String paramValue = request.getParameter(paramName);
            System.out.println(paramName+":"+paramValue);
        }
        // 放开拦截
        return true;
    }
    @Override
    public void postHandle(HttpServletRequest request,HttpServletResponse response,
                           Object handler, ModelAndView modelAndView) throws Exception {
        log.info("BodyInterceptor:postHandle");
    }
    @Override
    public void afterCompletion(HttpServletRequest request,HttpServletResponse response,
                                Object handler, Exception e) throws Exception {
        log.info("BodyInterceptor:afterCompletion");
    }
}
/** * 拦截器一 */ public class HeadInterceptor implements HandlerInterceptor { private static final Logger log = LoggerFactory.getLogger(HeadInterceptor.class); @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { log.info("HeadInterceptor:preHandle"); Iterator<String> headNames = request.getHeaderNames().asIterator(); log.info("request-header"); while (headNames.hasNext()){ String headName = headNames.next(); String headValue = request.getHeader(headName); System.out.println(headName+":"+headValue); } // 放开拦截 return true; } @Override public void postHandle(HttpServletRequest request,HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception { log.info("HeadInterceptor:postHandle"); } @Override public void afterCompletion(HttpServletRequest request,HttpServletResponse response, Object handler, Exception e) throws Exception { log.info("HeadInterceptor:afterCompletion"); } } /** * 拦截器二 */ public class BodyInterceptor implements HandlerInterceptor { private static final Logger log = LoggerFactory.getLogger(BodyInterceptor.class); @Override public boolean preHandle(HttpServletRequest request,HttpServletResponse response, Object handler) throws Exception { log.info("BodyInterceptor:preHandle"); Iterator<String> paramNames = request.getParameterNames().asIterator(); log.info("request-param"); while (paramNames.hasNext()){ String paramName = paramNames.next(); String paramValue = request.getParameter(paramName); System.out.println(paramName+":"+paramValue); } // 放开拦截 return true; } @Override public void postHandle(HttpServletRequest request,HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception { log.info("BodyInterceptor:postHandle"); } @Override public void afterCompletion(HttpServletRequest request,HttpServletResponse response, Object handler, Exception e) throws Exception { log.info("BodyInterceptor:afterCompletion"); } }

2、拦截器配置

自定义拦截器之后,还需要添加到web工程的配置文件中,可以通过实现WebMvcConfigurer接口,完成自定义的配置添加;

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {
/**
* 添加自定义拦截器
*/
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new HeadInterceptor()).addPathPatterns("/**");
registry.addInterceptor(new BodyInterceptor()).addPathPatterns("/**");
}
}
@Configuration
public class WebMvcConfig implements WebMvcConfigurer {

    /**
     * 添加自定义拦截器
     */
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new HeadInterceptor()).addPathPatterns("/**");
        registry.addInterceptor(new BodyInterceptor()).addPathPatterns("/**");
    }
}
@Configuration public class WebMvcConfig implements WebMvcConfigurer { /** * 添加自定义拦截器 */ @Override public void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(new HeadInterceptor()).addPathPatterns("/**"); registry.addInterceptor(new BodyInterceptor()).addPathPatterns("/**"); } }

五、测试工具

1、Swagger接口

添加上述的springdoc依赖之后,还可以在配置文件中简单定义一些信息,访问IP:端口/swagger-ui/index.html即可;

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {
/**
* 接口文档配置
*/
@Bean
public OpenAPI openAPI() {
return new OpenAPI()
.info(new Info().title("【boot-web】").description("Rest接口文档-2023-07-11")
.version("1.0.0"));
}
}
@Configuration
public class WebMvcConfig implements WebMvcConfigurer {

    /**
     * 接口文档配置
     */
    @Bean
    public OpenAPI openAPI() {
        return new OpenAPI()
                .info(new Info().title("【boot-web】").description("Rest接口文档-2023-07-11")
                .version("1.0.0"));
    }
}
@Configuration public class WebMvcConfig implements WebMvcConfigurer { /** * 接口文档配置 */ @Bean public OpenAPI openAPI() { return new OpenAPI() .info(new Info().title("【boot-web】").description("Rest接口文档-2023-07-11") .version("1.0.0")); } }

2、Junit测试

在个人的习惯上,Swagger接口文档更偏向在前后端对接的时候使用,而Junit单元测试更符合开发的时候使用,这里是对RestWeb中的接口进行测试;

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class RestWebTest {
@Autowired
private MockMvc mockMvc;
@Test
public void testGet () throws Exception {
// GET接口测试
MvcResult mvcResult = mockMvc
.perform(MockMvcRequestBuilders.get("/rest/get/1"))
.andReturn();
printMvcResult(mvcResult);
}
@Test
public void testPost () throws Exception {
// 参数模型
JsonMapper jsonMapper = new JsonMapper();
ParamBO param = new ParamBO(null,"单元测试",new Date()) ;
String paramJson = jsonMapper.writeValueAsString(param) ;
// Post接口测试
MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.post("/rest/post")
.contentType(MediaType.APPLICATION_JSON)
.accept(MediaType.APPLICATION_JSON).content(paramJson)).andReturn();
printMvcResult(mvcResult);
}
@Test
public void testPut () throws Exception {
// 参数模型
JsonMapper jsonMapper = new JsonMapper();
ParamBO param = new ParamBO(7,"Junit组件",new Date()) ;
String paramJson = jsonMapper.writeValueAsString(param) ;
// Put接口测试
MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.put("/rest/put")
.contentType(MediaType.APPLICATION_JSON)
.accept(MediaType.APPLICATION_JSON).content(paramJson)).andReturn();
printMvcResult(mvcResult);
}
@Test
public void testDelete () throws Exception {
// Delete接口测试
MvcResult mvcResult = mockMvc
.perform(MockMvcRequestBuilders.delete("/rest/delete/2"))
.andReturn();
printMvcResult(mvcResult);
}
/**
* 打印【MvcResult】信息
*/
private void printMvcResult (MvcResult mvcResult) throws Exception {
System.out.println("请求-URI【"+mvcResult.getRequest().getRequestURI()+"】");
System.out.println("响应-status【"+mvcResult.getResponse().getStatus()+"】");
System.out.println("响应-content【"+mvcResult.getResponse().getContentAsString(StandardCharsets.UTF_8)+"】");
}
}
@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class RestWebTest {

    @Autowired
    private MockMvc mockMvc;

    @Test
    public void testGet () throws Exception {
        // GET接口测试
        MvcResult mvcResult = mockMvc
                .perform(MockMvcRequestBuilders.get("/rest/get/1"))
                .andReturn();
        printMvcResult(mvcResult);
    }

    @Test
    public void testPost () throws Exception {
        // 参数模型
        JsonMapper jsonMapper = new JsonMapper();
        ParamBO param = new ParamBO(null,"单元测试",new Date()) ;
        String paramJson = jsonMapper.writeValueAsString(param) ;
        // Post接口测试
        MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.post("/rest/post")
                .contentType(MediaType.APPLICATION_JSON)
                .accept(MediaType.APPLICATION_JSON).content(paramJson)).andReturn();
        printMvcResult(mvcResult);
    }

    @Test
    public void testPut () throws Exception {
        // 参数模型
        JsonMapper jsonMapper = new JsonMapper();
        ParamBO param = new ParamBO(7,"Junit组件",new Date()) ;
        String paramJson = jsonMapper.writeValueAsString(param) ;
        // Put接口测试
        MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.put("/rest/put")
                .contentType(MediaType.APPLICATION_JSON)
                .accept(MediaType.APPLICATION_JSON).content(paramJson)).andReturn();
        printMvcResult(mvcResult);
    }

    @Test
    public void testDelete () throws Exception {
        // Delete接口测试
        MvcResult mvcResult = mockMvc
                .perform(MockMvcRequestBuilders.delete("/rest/delete/2"))
                .andReturn();
        printMvcResult(mvcResult);
    }

    /**

    private void printMvcResult (MvcResult mvcResult) throws Exception {
        System.out.println("请求-URI【"+mvcResult.getRequest().getRequestURI()+"】");
        System.out.println("响应-status【"+mvcResult.getResponse().getStatus()+"】");
        System.out.println("响应-content【"+mvcResult.getResponse().getContentAsString(StandardCharsets.UTF_8)+"】");
