在spring+springMvc+mabatis框架下集成swagger

我是在ssm框架下集成swagger的，具体的ssm搭建可以看这篇博文：

Intellij Idea下搭建基于Spring+SpringMvc+MyBatis的WebApi接口架构

本项目的GitHub地址：https://github.com/chenyangsocool/ssm.git

接下去就正式开始了：

1.通过maven导入相关swagger的jar包：

    <!-- swagger -->
    <dependency>
      <groupId>io.springfox</groupId>
      <artifactId>springfox-swagger2</artifactId>
      <version>2.6.1</version>
    </dependency>
    <dependency>
      <groupId>io.springfox</groupId>
      <artifactId>springfox-swagger-ui</artifactId>
      <version>2.6.1</version>
    </dependency>
    <dependency>
      <groupId>com.fasterxml.jackson.core</groupId>
      <artifactId>jackson-core</artifactId>
      <version>2.6.5</version>
    </dependency>
    <dependency>
      <groupId>com.fasterxml.jackson.core</groupId>
      <artifactId>jackson-databind</artifactId>
      <version>2.6.5</version>
    </dependency>
    <dependency>
      <groupId>com.fasterxml.jackson.core</groupId>
      <artifactId>jackson-annotations</artifactId>
      <version>2.6.5</version>
    </dependency>
    <!-- /swagger -->

2.在com.chenyangsocool.ssm.tools下新建swagger/Swagger2Config.java：

package com.chenyangsocool.ssm.tools.swagger;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import io.swagger.annotations.ApiOperation;
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;

@Configuration      //让Spring来加载该类配置
@EnableWebMvc       //启用Mvc，非springboot框架需要引入注解@EnableWebMvc
@EnableSwagger2     //启用Swagger2
public class Swagger2Config {
    @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("com.xia.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 RESTful APIs")
                .description("This API Document is based on RESTful Style, The description is detail and auto-generation, It's very friendly for developers.")
                .termsOfServiceUrl("http://www.cnblogs.com/chenyangsocool/")
                .contact("Young")
                .version("1.0.0")
                .build();
    }
}

3.在实体类中创建注释，以Test实体类为例：

package com.chenyangsocool.ssm.model;

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

@ApiModel(value="Test",description="Test")//对类进行swagger注解
public class Test {
    @ApiModelProperty(value="测试id",name="id")//对类的字段属性进行swagger注解
    private int id;

    @ApiModelProperty(value="测试内容",name="context")
    private String context;

    @ApiModelProperty(value="测试内容的浏览数",name="viewCount")
    private int viewCount;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getContext() {
        return context;
    }

    public void setContext(String context) {
        this.context = context;
    }

    public int getViewCount() {
        return viewCount;
    }

    public void setViewCount(int viewCount) {
        this.viewCount = viewCount;
    }

    @Override
    public String toString() {
        return "Test{" +
                "id=" + id +
                ", context='" + context + '\'' +
                ", viewCount=" + viewCount +
                '}';
    }
}

4.在TestController中添加swagger相关代码：

package com.chenyangsocool.ssm.controller;

import com.chenyangsocool.ssm.model.Test;
import com.chenyangsocool.ssm.service.ITestService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;

@Controller
@RequestMapping("/test")
@Api(value = "测试信息", tags = {"测试相关接口"})//swagger控制器说明注解
public class TestController {

    @Resource
    private ITestService testService;

    @RequestMapping("/index_page")
    public String showIndex(HttpServletRequest request, Model model) {
        int id = Integer.parseInt(request.getParameter("id"));
        Test test = this.testService.getModelById(id);
        //绑定对象到test/index.jsp
        model.addAttribute("test", test);
        return "test/index";
    }

    @RequestMapping("/index_api")
    @ResponseBody
    @ApiOperation(value = "获取单个测试实例", notes = "传入一个id，获取该id对应的实例。",httpMethod = "GET")//swagger方法注解
    public Test Index(HttpServletRequest request,Model model) {
        int id = Integer.parseInt(request.getParameter("id"));
        return this.testService.getModelById(id);
    }
}
