ssm集成swagger

什么事swagger：【不一一赘述了】

集成的注意事项：

这里是采用ssm+swagger的基础方式，且swagger为2.0以上的版本。

步骤：

1. 引入依赖

        
            io.springfox
            springfox-swagger2
            2.9.2
        
        
        
            io.springfox
            springfox-swagger-ui
            2.9.2
        

有的博客是引入以下的依赖，此依赖为1.0的版本，两种依赖不能同时引入，会出现意想不到的BUG。

        
            com.mangofactory
            swagger-springmvc
            1.0.2
        

2.下载swagger源码

下载地址： 点击下载swagger

https://github.com/swagger-api/swagger-ui/tree/v2.1.5

3.在web项目webapp下新建文件夹swagger，将下载的源码导入到文件夹下：


修改index.html页面：如图所示。
1.0版本可以简写为：”/api-docs”
2.0版本简写为：”/v2/api-docs”

4,编写swagger工具类

package com.zengqiang.utils;

import io.swagger.annotations.ApiOperation;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
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;

/**
 * @Author: [email protected]
 * @Date: 2018/12/30 10:30
 * @Version: 1.0
 * @Desc: TODO
 **/
@Configuration
@EnableSwagger2
@EnableWebMvc
public class SwaggerConfig {

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo()).select()
                //扫描指定包中的swagger注解
                //.apis(RequestHandlerSelectors.basePackage("cn.exrick.controller"))
                //扫描所有有注解的api，用这种方式更灵活
                .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("ssm-single Api Documentation")
                .description("ssm-single项目后台API接口文档")
                .termsOfServiceUrl("https://www.baidu.com/")
                .license("[email protected]")
                .version("1.0.0")
                .build();
    }


}

5,编写API

package com.zengqiang.controller;

import com.zengqiang.student.service.StudentService;
import com.zengqiang.utils.ModelAndView;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
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.ResponseBody;

/**
 * @Author: [email protected]
 * @Date: 2018/12/29 14:47
 * @Version: 1.0
 * @Desc: TODO
 **/
@Controller
@RequestMapping("/student")
@Api(value = "student的操作类", description = "学生类")
public class StudentController {
    @Autowired
    private StudentService studentService;

    @RequestMapping(value = "/s.json", method = {RequestMethod.POST, RequestMethod.GET})
    @ResponseBody
    @ApiOperation(value = "根据id查询学生信息", notes = "查询学生", response = ModelAndView.class)
    public ModelAndView selectStudentById(@ApiParam(required = true, value = "学生ID", name = "id") @RequestParam(value = "id") Integer id) {
        return studentService.queryStudentById(id);
    }
}

6，springSwaggerConfig加载到spring容器
在项目的配置文件applicantContext.xml中加入：

好了，到这里就大工告成了。
