swagger用于定义API文档。
好处:
1、项目结构
和上一节一样,没有改变。
2、pom.xml
引入了两个jar。
io.springfox
springfox-swagger2
2.2.2
io.springfox
springfox-swagger-ui
2.2.2
3、Application.java
package com.xxx.firstboot;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
@SpringBootApplication //same as @Configuration+@EnableAutoConfiguration+@ComponentScan
@EnableSwagger2 //启动swagger注解
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
说明:
4、UserController.java
package com.xxx.firstboot.web;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestHeader;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import com.xxx.firstboot.domain.User;
import com.xxx.firstboot.service.UserService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiResponse;
import io.swagger.annotations.ApiResponses;
@RestController
@RequestMapping("/user")
@Api("userController相关api")
public class UserController {
@Autowired
private UserService userService;
// @Autowired
// private MyRedisTemplate myRedisTemplate;
@ApiOperation("获取用户信息")
@ApiImplicitParams({
@ApiImplicitParam(paramType="header",name="username",dataType="String",required=true,value="用户的姓名",defaultValue="zhaojigang"),
@ApiImplicitParam(paramType="query",name="password",dataType="String",required=true,value="用户的密码",defaultValue="wangna")
})
@ApiResponses({
@ApiResponse(code=400,message="请求参数没填好"),
@ApiResponse(code=404,message="请求路径没有或页面跳转路径不对")
})
@RequestMapping(value="/getUser",method=RequestMethod.GET)
public User getUser(@RequestHeader("username") String username, @RequestParam("password") String password) {
return userService.getUser(username,password);
}
// @RequestMapping("/testJedisCluster")
// public User testJedisCluster(@RequestParam("username") String username){
// String value = myRedisTemplate.get(MyConstants.USER_FORWARD_CACHE_PREFIX, username);
// if(StringUtils.isBlank(value)){
// myRedisTemplate.set(MyConstants.USER_FORWARD_CACHE_PREFIX, username, JSON.toJSONString(getUser()));
// return null;
// }
// return JSON.parseObject(value, User.class);
// }
}
说明:
以上这些就是最常用的几个注解了。
需要注意的是:
如果ApiImplicitParam中的phone的paramType是query的话,是无法注入到rest路径中的,而且如果是path的话,是不需要配置ApiImplicitParam的,即使配置了,其中的value="手机号"也不会在swagger-ui展示出来。
具体其他的注解,查看:
https://github.com/swagger-api/swagger-core/wiki/Annotations#apimodel
测试:
启动服务,浏览器输入"http://localhost:8080/swagger-ui.html"
最上边一个红框:@Api
GET红框:method=RequestMethod.GET
右边红框:@ApiOperation
parameter红框:@ApiImplicitParams系列注解
response messages红框:@ApiResponses系列注解
输入参数后,点击"try it out!",查看响应内容:
