SpringBoot 和 Swagger 集成

一、pom文件引用

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.example</groupId>
    <artifactId>demo</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>

        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
        <springfox.swagger2.version>2.6.1</springfox.swagger2.version>
        <springfox.swagger.ui.version>2.6.1</springfox.swagger.ui.version>
    </properties>

            <version>${springfox.swagger.ui.version}</version>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>

            </plugin>
        </plugins>
    </build>


</project>

二、POJO 类

package com.dtyunxi.swagger.demo.pojo;

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;

import java.io.Serializable;

@ApiModel(value = "用户实体")
public class Person implements Serializable {
    @ApiModelProperty(value = "姓名", example = "张三")
    private String name;
    @ApiModelProperty(value = "年龄", example = "18")
    private Integer age;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }
}

三、控制层

package com.dtyunxi.swagger.demo.controller;

import com.dtyunxi.swagger.demo.pojo.Person;
import io.swagger.annotations.*;
import org.springframework.web.bind.annotation.*;

@RestController
@Api("测试集成swagger")
public class Controller {
    @RequestMapping(value = "/user/{str}", method = RequestMethod.GET)
    @ApiOperation(value= "返回参数值")
    public String print(@PathVariable(name = "str") @ApiParam(value = "字符串") String str){
        return str;
    }
    @RequestMapping(value = "/user/print", method = RequestMethod.POST)
    @ApiOperation(value= "POST 对象传参")
    public String print2(@ApiParam(name = "用户") @RequestBody Person person){
        return "POST";
    }
}

四、启动类

package com.dtyunxi.swagger.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

五、Swagger 常用注解

注释汇总

作用范围	API	使用位置
对象属性	@ApiModelProperty	用在出入参数对象的字段上
协议集描述	@Api	用于controller类上
协议描述	@ApiOperation	用在controller的方法上
Response集	@ApiResponses	用在controller的方法上
Response	@ApiResponse	用在 @ApiResponses里边
非对象参数集	@ApiImplicitParams	用在controller的方法上
非对象参数描述	@ApiImplicitParam	用在@ApiImplicitParams的方法里边
描述返回对象的意义	@ApiModel	用在返回对象类上

 @ApiOperation("信息软删除")
    @ApiResponses({ @ApiResponse(code = CommonStatus.OK, message = "操作成功"),
            @ApiResponse(code = CommonStatus.EXCEPTION, message = "服务器内部异常"),
            @ApiResponse(code = CommonStatus.FORBIDDEN, message = "权限不足") })
    @ApiImplicitParams({ @ApiImplicitParam(paramType = "query", dataType = "Long", name = "id", value = "信息id", required = true) })
    @RequestMapping(value = "/remove.json", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
    public RestfulProtocol remove(Long id) {

@ApiImplicitParam

属性	取值	作用
paramType		查询参数类型
	path	以地址的形式提交数据
	query	直接跟参数完成自动映射赋值
	body	以流的形式提交 仅支持POST
	header	参数在request headers 里边提交
	form	以form表单的形式提交 仅支持POST
dataType		参数的数据类型 只作为标志说明，并没有实际验证
	Long
	String
name		接收参数名
value		接收参数的意义描述
required		参数是否必填
	true	必填
	false	非必填
defaultValue		默认值

paramType 示例详解

path

 @RequestMapping(value = "/findById1/{id}", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_UTF8_VALUE)

 @PathVariable(name = "id") Long id

body

  @ApiImplicitParams({ @ApiImplicitParam(paramType = "body", dataType = "MessageParam", name = "param", value = "信息参数", required = true) })
  @RequestMapping(value = "/findById3", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_UTF8_VALUE, consumes = MediaType.APPLICATION_JSON_VALUE)

  @RequestBody MessageParam param

  提交的参数是这个对象的一个json，然后会自动解析到对应的字段上去，也可以通过流的形式接收当前的请求数据，但是这个和上面的接收方式仅能使用一个（用@RequestBody之后流就会关闭了）

header

  @ApiImplicitParams({ @ApiImplicitParam(paramType = "header", dataType = "Long", name = "id", value = "信息id", required = true) }) 

   String idstr = request.getHeader("id");
        if (StringUtils.isNumeric(idstr)) {
            id = Long.parseLong(idstr);
        }

Form

@ApiImplicitParams({ @ApiImplicitParam(paramType = "form", dataType = "Long", name = "id", value = "信息id", required = true) })
 @RequestMapping(value = "/findById5", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_UTF8_VALUE, consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
