0.Spring MVC配置文件中的配置
- <!-- 设置使用注解的类所在的jar包,只加载controller类 -->
- <span style="white-space:pre"> </span><context:component-scan base-package="com.jay.plat.config.controller" />
- <!-- 使用 Swagger Restful API文档时,添加此注解 -->
- <mvc:default-servlet-handler />
1.maven依赖
- <!-- 构建Restful API -->
- <dependency>
- <groupId>io.springfox</groupId>
- <artifactId>springfox-swagger2</artifactId>
- <version>2.4.0</version>
- </dependency>
- <dependency>
- <groupId>io.springfox</groupId>
- <artifactId>springfox-swagger-ui</artifactId>
- <version>2.4.0</version>
- </dependency>
2.Swagger配置文件
- package com.jay.plat.config.util;
- import org.springframework.context.annotation.Bean;
- import org.springframework.context.annotation.ComponentScan;
- import org.springframework.context.annotation.Configuration;
- import org.springframework.web.servlet.config.annotation.EnableWebMvc;
- import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
- import springfox.documentation.builders.ApiInfoBuilder;
- import springfox.documentation.builders.PathSelectors;
- import springfox.documentation.builders.RequestHandlerSelectors;
- import springfox.documentation.service.ApiInfo;
- import springfox.documentation.spi.DocumentationType;
- import springfox.documentation.spring.web.plugins.Docket;
- import springfox.documentation.swagger2.annotations.EnableSwagger2;
- /*
- * Restful API 访问路径:
- * http://IP:port/{context-path}/swagger-ui.html
- * eg:http://localhost:8080/jd-config-web/swagger-ui.html
- */
- @EnableWebMvc
- @EnableSwagger2
- @ComponentScan(basePackages = {"com.<span style="font-family:Arial, Helvetica, sans-serif;">jay.</span>plat.config.controller"})
- @Configuration
- public class RestApiConfig extends WebMvcConfigurationSupport{
- @Bean
- public Docket createRestApi() {
- return new Docket(DocumentationType.SWAGGER_2)
- .apiInfo(apiInfo())
- .select()
- .apis(RequestHandlerSelectors.basePackage("com.jay.plat.config.controller"))
- .paths(PathSelectors.any())
- .build();
- }
- private ApiInfo apiInfo() {
- return new ApiInfoBuilder()
- .title("Spring 中使用Swagger2构建RESTful APIs")
- .termsOfServiceUrl("http://blog.csdn.net/he90227")
- .contact("逍遥飞鹤")
- .version("1.1")
- .build();
- }
- }
配置说明:
- @Configuration 配置注解,自动在本类上下文加载一些环境变量信息
- @EnableWebMvc
- @EnableSwagger2 使swagger2生效
- @ComponentScan("com.myapp.packages") 需要扫描的包路径
3.Controller中使用注解添加API文档
- package com.jay.spring.boot.demo10.swagger2.controller;
- import java.util.ArrayList;
- import java.util.Collections;
- import java.util.HashMap;
- import java.util.List;
- import java.util.Map;
- import org.springframework.web.bind.annotation.PathVariable;
- import org.springframework.web.bind.annotation.RequestBody;
- import org.springframework.web.bind.annotation.RequestMapping;
- import org.springframework.web.bind.annotation.RequestMethod;
- import org.springframework.web.bind.annotation.RestController;
- import com.jay.spring.boot.demo10.swagger2.bean.User;
- import io.swagger.annotations.ApiImplicitParam;
- import io.swagger.annotations.ApiImplicitParams;
- import io.swagger.annotations.ApiOperation;
- @RestController
- @RequestMapping(value = "/users") // 通过这里配置使下面的映射都在/users下,可去除
- public class UserController {
- static Map<Long, User> users = Collections.synchronizedMap(new HashMap<Long, User>());
- @ApiOperation(value = "获取用户列表", notes = "")
- @RequestMapping(value = { "" }, method = RequestMethod.GET)
- public List<User> getUserList() {
- List<User> r = new ArrayList<User>(users.values());
- return r;
- }
- @ApiOperation(value = "创建用户", notes = "根据User对象创建用户")
- @ApiImplicitParam(name = "user", value = "用户详细实体user", required = true, dataType = "User")
- @RequestMapping(value = "", method = RequestMethod.POST)
- public String postUser(@RequestBody User user) {
- users.put(user.getId(), user);
- return "success";
- }
- @ApiOperation(value = "获取用户详细信息", notes = "根据url的id来获取用户详细信息")
- @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long")
- @RequestMapping(value = "/{id}", method = RequestMethod.GET)
- public User getUser(@PathVariable Long id) {
- return users.get(id);
- }
- @ApiOperation(value = "更新用户详细信息", notes = "根据url的id来指定更新对象,并根据传过来的user信息来更新用户详细信息")
- @ApiImplicitParams({ @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long"),
- @ApiImplicitParam(name = "user", value = "用户详细实体user", required = true, dataType = "User") })
- @RequestMapping(value = "/{id}", method = RequestMethod.PUT)
- public String putUser(@PathVariable Long id, @RequestBody User user) {
- User u = users.get(id);
- u.setName(user.getName());
- u.setAge(user.getAge());
- users.put(id, u);
- return "success";
- }
- @ApiOperation(value = "删除用户", notes = "根据url的id来指定删除对象")
- @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long")
- @RequestMapping(value = "/{id}", method = RequestMethod.DELETE)
- public String deleteUser(@PathVariable Long id) {
- users.remove(id);
- return "success";
- }
- }
4.效果展示
访问路径:
- Restful API 访问路径:
- * http://IP:port/{context-path}/swagger-ui.html
- * eg:http://localhost:8080/jd-config-web/swagger-ui.html
