springboot swagger 整合

Swagger 是一个规范和完整的框架，用于生成、描述、调用和可视化 RESTful 风格的 Web 服务。 文件的方法，参数和模型紧密集成到服务器端的代码，允许API来始终保持同步。

作用：

1. 接口的文档在线自动生成。

2. 功能测试。

1.添加pom.xml

<dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.7.0</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.7.0</version>
        </dependency>

2.在启动类同级增加类

package com;

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.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class Swagger2 {
//swagger2的配置文件，这里可以配置swagger2的一些基本的内容，比如扫描的包等等
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                //为当前包路径
                .apis(RequestHandlerSelectors.basePackage("com.taiji.demo.controller"))
                .paths(PathSelectors.any())
                .build();
    }
    //构建 api文档的详细信息函数,注意这里的注解引用的是哪个
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                //页面标题
                .title("系统API接口")

                //创建人
                .contact(new Contact("zhangyg", "www.redxun.com", "zhangyg@redxun.cn"))
                //版本号
                .version("1.0")
                //描述
                .description("系统API接口")
                .build();
    }

}

3.编辑java 文件

package com.taiji.demo.controller;

import org.springframework.beans.factory.annotation.Autowired;
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.alibaba.fastjson.JSONObject;
import com.taiji.core.util.IdUtil;
import com.taiji.demo.model.SaleOrder;
import com.taiji.demo.service.SaleOrderService;

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;
import io.swagger.annotations.ApiResponse;
import io.swagger.annotations.ApiResponses;

@RestController
@Api(value="销售订单API接口")
public class SaleOrderController {

        @Autowired
        private SaleOrderService saleOrderService;

        @ApiOperation(value="添加订单",notes="添加订单描述")
        @RequestMapping(value="/add",method={RequestMethod.POST,RequestMethod.GET})
        public void add(@ApiParam(value = "用户数据",
                        required = true,
                        type="JSONObject",
                        example="{\"name\":\"A\",\"userId\":\"B\",\"total\":\"100\"}") @RequestBody JSONObject json){
            SaleOrder order=new SaleOrder();
            order.setId(IdUtil.getId());
            order.setName(json.getString("name"));
            order.setCreator(json.getString("userId"));
            order.setTotal(json.getDouble("total"));
            saleOrderService.create(order);
        }

        @ApiOperation(value="根据ID查看明细",notes="根据ID查看明细")
        @ApiImplicitParams(value={
            @ApiImplicitParam(name="id",value="订单ID",required=true,dataType="String")
        })
        @RequestMapping(value="/get/{id}",method=RequestMethod.GET)
        public SaleOrder get(@PathVariable(value="id") String id){
            SaleOrder order= saleOrderService.get(id);
            return order;
        }

        @RequestMapping(value="/page/{page}",method=RequestMethod.GET)
        @ApiResponses({
            @ApiResponse(response=JSONObject.class, code = 200, message = "订单列表")
        })
        public JSONObject page(@PathVariable(value="page") int page){
            JSONObject order= saleOrderService.getAll(page,10);
            return order;
        }
}

4.访问平台列表

http://localhost:8000/demo/swagger-ui.html#/sale45order45controller

5.在线调试接口

输入好参数后，点击try it out 按钮，可以对代码进行调试。
