SpringMvc整合Swagger（spring版本在4.1.8以上，深深的痛）

1.先搭建好springmvc的环境
2.修改pom文件

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

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

3.也需要引入jackson的包
4.定义一个swagger的配置类

@EnableWebMvc
@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket buildDocket() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.basePackage("jk.zmn.mvc.controller")) //要扫描的API(Controller)基础包
                .paths(PathSelectors.any()) // and by paths
                .build();

    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("接口列表 v1.1.0") // 任意，请稍微规范点
                .description("接口测试") // 任意，请稍微规范点
                .termsOfServiceUrl("http://localhost:8080/swagger-ui.html") // 将“url”换成自己的ip:port
                .contact("laowu") // 无所谓（这里是作者的别称）
                .version("1.1.0")
                .build();
    }
}

5.修改springmvc的配置文件,放行一些静态资源

  <mvc:resources location="classpath:/META-INF/resources/" mapping="swagger-ui.html"/>
    <mvc:resources location="classpath:/META-INF/resources/webjars/" mapping="/webjars/**"/>
    <!--&lt;!&ndash; 添加扫描配置类 &ndash;&gt;-->
    <bean class="jk.zmn.mvc.config.SwaggerConfig" />

6.新建controller，定义一些相关的文档

@RestController
@RequestMapping("test")
@Api(value = "Test")
public class TestController {

    @RequestMapping("index")
    @ApiOperation(value = "进入首页面")
    public String index(){
        return "index";
    }

}

7.访问http://ip:端口/项目名/swagger-ui.html即可

SpringBoot整合swagger

1.新建springboot项目
2.引入swagger的jar包

<!-- Swagger -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.7.0</version>
        </dependency>

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

3.定义swagger的配置类

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket buildDocket() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.basePackage("jk.zmn.swaggerspringboot.controller")) //要扫描的API(Controller)基础包
                .paths(PathSelectors.any()) // and by paths
                .build()
                .apiInfo(buildApiInf());
    }

    private ApiInfo buildApiInf() {
        return new ApiInfoBuilder()
                .title("Spring Boot中使用Swagger2 UI构建API文档")
                .contact("test")
                .version("1.0.0")
                .build();
    }
}

4.自定义controller生成文档
5.访问http://ip:端口/项目名/swagger-ui.html即可
