一、Swagger2简介
1、Swagger2优点
整合到Spring Boot中,构建强大RESTful API文档。省去接口文档管理工作,修改代码,自动更新,Swagger2也提供了强大的页面测试功能来调试RESTful API。
2、Swagger2常用注解
Api:修饰整个类,描述Controller的作用
ApiOperation:描述一个类的一个方法,或者说一个接口
ApiParam:单个参数描述
ApiModel:用对象来接收参数
ApiProperty:用对象接收参数时,描述对象的一个字段
ApiResponse:HTTP响应其中1个描述
ApiResponses:HTTP响应整体描述
ApiIgnore:使用该注解忽略这个API
ApiError :发生错误返回的信息
ApiImplicitParam:一个请求参数
ApiImplicitParams:多个请求参数
二、与SpringBoot2.0 整合
1、核心依赖
spring-boot:2.1.3.RELEASE
swagger:2.6.1
2、Swagger2 配置
import org.springframework.context.annotation.Bean;
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;
/**
* Swagger 配置文件
*/
@Configuration
public class SwaggerConfig {
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("com.swagger.two"))
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("SpringBoot利用Swagger构建API文档")
.description("使用RestFul风格, 创建人:知了一笑")
.termsOfServiceUrl("https://github.com/cicadasmile")
.version("version 1.0")
.build();
}
}
3、启动类添加注解
@EnableSwagger2
@SpringBootApplication
public class SwaggerApplication {
public static void main(String[] args) {
SpringApplication.run(SwaggerApplication.class,args) ;
}
}
4、启动效果图
三、增删改查案例
1、添加用户
(1)、代码块
@ApiOperation(value="添加用户", notes="创建新用户")
@ApiImplicitParam(name = "user", value = "用户详细实体user", required = true, dataType = "User")
@RequestMapping(value = "/addUser", method = RequestMethod.POST)
public ResponseEntity addUser (@RequestBody User user){
JsonResult result = new JsonResult();
try {
users.put(user.getId(), user);
result.setResult(user.getId());
result.setStatus("ok");
} catch (Exception e) {
result.setResult("服务异常");
result.setStatus("500");
e.printStackTrace();
}
return ResponseEntity.ok(result);
}
(2)、效果图
2、用户列表
(1)、代码块
@ApiOperation(value="用户列表", notes="查询用户列表")
@RequestMapping(value = "/getUserList", method = RequestMethod.GET)
public ResponseEntity getUserList (){
JsonResult result = new JsonResult();
try {
List userList = new ArrayList<>(users.values());
result.setResult(userList);
result.setStatus("200");
} catch (Exception e) {
result.setResult("服务异常");
result.setStatus("500");
e.printStackTrace();
}
return ResponseEntity.ok(result);
}
(2)、效果图
3、用户查询
(1)、代码块
@ApiOperation(value="用户查询", notes="根据ID查询用户")
@ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Integer", paramType = "path")
@RequestMapping(value = "/getUserById/{id}", method = RequestMethod.GET)
public ResponseEntity getUserById (@PathVariable(value = "id") Integer id){
JsonResult result = new JsonResult();
try {
User user = users.get(id);
result.setResult(user);
result.setStatus("200");
} catch (Exception e) {
result.setResult("服务异常");
result.setStatus("500");
e.printStackTrace();
}
return ResponseEntity.ok(result);
}
(2)、效果图
4、更新用户
(1)、代码块
@ApiOperation(value="更新用户", notes="根据Id更新用户信息")
@ApiImplicitParams({
@ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long",paramType = "path"),
@ApiImplicitParam(name = "user", value = "用户对象user", required = true, dataType = "User")
})
@RequestMapping(value = "/updateById/{id}", method = RequestMethod.PUT)
public ResponseEntity updateById (@PathVariable("id") Integer id, @RequestBody User user){
JsonResult result = new JsonResult();
try {
User user1 = users.get(id);
user1.setUsername(user.getUsername());
user1.setAge(user.getAge());
users.put(id, user1);
result.setResult(user1);
result.setStatus("ok");
} catch (Exception e) {
result.setResult("服务异常");
result.setStatus("500");
e.printStackTrace();
}
return ResponseEntity.ok(result);
}
(2)、效果图
5、删除用户
(1)、代码块
@ApiOperation(value="删除用户", notes="根据id删除指定用户")
@ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long", paramType = "path")
@RequestMapping(value = "/deleteById/{id}", method = RequestMethod.DELETE)
public ResponseEntity deleteById (@PathVariable(value = "id") Integer id){
JsonResult result = new JsonResult();
try {
users.remove(id);
result.setResult(id);
result.setStatus("ok");
} catch (Exception e) {
result.setResult("服务异常");
result.setStatus("500");
e.printStackTrace();
}
return ResponseEntity.ok(result);
}
