一、添加依赖

<!--SpringBoot使用Swagger2构建API文档的依赖--> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>2.7.0</version> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>2.7.0</version> </dependency>

二、创建Swagger2配置类

package com.offcn.config;import org.springframework.context.annotation.Configuration;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;@Configuration//表示该类为一个配置类，相当于spring中的xml配置文件@EnableSwagger2 //开启在线文档public class SwaggerConfig { //1.声明 api 文档的属性 private ApiInfo apiInfo() { return new ApiInfoBuilder() .title("Spring Boot中使用Swagger2构建RESTful APIs") .description("优就业") .termsOfServiceUrl("http://.offcn.entity.User;import io.swagger.annotations.ApiImplicitParam;import io.swagger.annotations.ApiImplicitParams;import io.swagger.annotations.ApiOperation;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.DeleteMapping;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;@RequestMapping("/rest")@RestControllerpublic class RestFulController { @Autowired private UserDao userDao; @GetMapping("/getUserById") @ApiOperation(value="查找指定id用户信息", notes="根据id查找用户信息") @ApiImplicitParams({ @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Integer"), }) public User getUserById(Integer id){ User user = userDao.getOne(id); return user; } @DeleteMapping("/del") @ApiOperation(value="删除指定id用户信息", notes="根据id删除用户信息") @ApiImplicitParams({ @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Integer"), }) public String delUserById(Integer id){ userDao.deleteById(id); return "success"; }}

四、查看Swagger2文档

重启项目

访问：

http://localhost:8080/swagger-ui.html
