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 -->  <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 />

<mvc:resources mapping="swagger-ui.html" location="classpath:/META-INF/resources/"/>  <mvc:resources mapping="/webjars/**" location="classpath:/META-INF/resources/webjars/"/>

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>

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.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

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";      }    }

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
