SpringMvc4集成swagger2

添加Swagger2依赖

在pom.xml中加入Swagger2的依赖

<dependency>            <groupId>io.springfox</groupId>            <artifactId>springfox-swagger2</artifactId>            <version>2.5.0</version>        </dependency>        <dependency>            <groupId>io.springfox</groupId>            <artifactId>springfox-swagger-ui</artifactId>            <version>2.5.0</version>        </dependency>         <!--jackson用于将springfox返回的文档对象转换成JSON字符串-->        <dependency>            <groupId>com.fasterxml.jackson.core</groupId>            <artifactId>jackson-annotations</artifactId>            <version>2.5.0</version>        </dependency>        <dependency>            <groupId>com.fasterxml.jackson.core</groupId>            <artifactId>jackson-databind</artifactId>            <version>2.5.0</version>        </dependency>        <dependency>            <groupId>com.fasterxml.jackson.core</groupId>            <artifactId>jackson-core</artifactId>            <version>2.5.0</version>        </dependency>

创建Swagger2配置类

package com.leo.ows.util;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.config.annotation.EnableWebMvc;import springfox.documentation.builders.ApiInfoBuilder;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;@EnableWebMvc@EnableSwagger2@ComponentScan(basePackages = {"com.leo.ows.action"})  @Configurationpublic class MySwaggerConfig {    @Bean    public Docket petApi() {        return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select()               .apis(RequestHandlerSelectors.basePackage("com.leo.ows.action")).build();    }    private ApiInfo apiInfo() {        return new ApiInfoBuilder().title("服务平台 API").description("").termsOfServiceUrl("http://localhost:8080").version("1.0").build();    }}

配置静态文件访问

<mvc:resources location="classpath:/META-INF/resources/" mapping="swagger-ui.html"/>  <mvc:resources location="classpath:/META-INF/resources/webjars/" mapping="/webjars/**"/>  

package com.leo.ows.action;import javax.annotation.Resource;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import com.leo.ows.entity.Article;import com.leo.ows.servise.ArticleServise;import io.swagger.annotations.Api;import io.swagger.annotations.ApiOperation;@Api(description = "文章控制器")@Controllerpublic class ArticleAction {    @Resource    private ArticleServise articleServise;    @ApiOperation(value = "增加文章", httpMethod = "POST")    @RequestMapping(value = "/articleAdd", method = RequestMethod.POST)    public String ArticleAdd(Model model, Article article) {        System.out.println(article.getTitle());        articleServise.AddArticle(article);        return "index";    }}

常用到的注解有：
Api
ApiModel
ApiModelProperty
ApiOperation
ApiParam
ApiResponse
ApiResponses
ResponseHeader
api标记
Api 标记可以标记一个Controller类做为swagger 文档资源，使用方式：

@Api(value = “/user”, description = “Operations about user”)
与Controller注解并列使用。 属性配置：

属性名称 备注

在SpringMvc中的配置如下：

@Controller@RequestMapping(value = "/api/pet", produces = {APPLICATION_JSON_VALUE, APPLICATION_XML_VALUE})@Api(value = "/pet", description = "Operations about pets")public class PetController {}

ApiOperation标记
ApiOperation每一个url资源的定义,使用方式：

@ApiOperation(          value = "Find purchase order by ID",          notes = "For valid response try integer IDs with value <= 5 or > 10\. Other values will generated exceptions",          response = Order,          tags = {"Pet Store"})

与Controller中的方法并列使用。
属性配置：

属性名称 备注

在SpringMvc中的配置如下：

@RequestMapping(value = "/order/{orderId}", method = GET)  @ApiOperation(      value = "Find purchase order by ID",      notes = "For valid response try integer IDs with value <= 5 or > 10\. Other values will generated exceptions",      response = Order.class,      tags = { "Pet Store" })   public ResponseEntity<Order> getOrderById(@PathVariable("orderId") String orderId)      throws NotFoundException {    Order order = storeData.get(Long.valueOf(orderId));    if (null != order) {      return ok(order);    } else {      throw new NotFoundException(404, "Order not found");    }  }

ApiParam标记
ApiParam请求属性,使用方式：

public ResponseEntity<User> createUser(@RequestBody @ApiParam(value = "Created user object", required = true) User user)

与Controller中的方法并列使用。

属性配置：

在SpringMvc中的配置如下：

 public ResponseEntity<Order> getOrderById(      @ApiParam(value = "ID of pet that needs to be fetched", allowableValues = "range[1,5]", required = true)      @PathVariable("orderId") String orderId)

ApiResponse
ApiResponse：响应配置，使用方式：

@ApiResponse(code = 400, message = “Invalid user supplied”)
与Controller中的方法并列使用。 属性配置：

属性名称 备注
code http的状态码
message 描述
response 默认响应类 Void
reference 参考ApiOperation中配置
responseHeaders 参考 ResponseHeader 属性配置说明
responseContainer 参考ApiOperation中配置
在SpringMvc中的配置如下：

 @RequestMapping(value = "/order", method = POST)  @ApiOperation(value = "Place an order for a pet", response = Order.class)  @ApiResponses({ @ApiResponse(code = 400, message = "Invalid Order") })  public ResponseEntity<String> placeOrder(      @ApiParam(value = "order placed for purchasing the pet", required = true) Order order) {    storeData.add(order);    return ok("");  }

ApiResponses
ApiResponses：响应集配置，使用方式：

@ApiResponses({ @ApiResponse(code = 400, message = “Invalid Order”) })
与Controller中的方法并列使用。 属性配置：

属性名称 备注
value 多个ApiResponse配置
在SpringMvc中的配置如下：

 @RequestMapping(value = "/order", method = POST)  @ApiOperation(value = "Place an order for a pet", response = Order.class)  @ApiResponses({ @ApiResponse(code = 400, message = "Invalid Order") })  public ResponseEntity<String> placeOrder(      @ApiParam(value = "order placed for purchasing the pet", required = true) Order order) {    storeData.add(order);    return ok("");  }

ResponseHeader
响应头设置，使用方法

@ResponseHeader(name="head1",description="response head conf")

与Controller中的方法并列使用。 属性配置：

属性名称 备注
name 响应头名称
description 头描述
response 默认响应类 Void
responseContainer 参考ApiOperation中配置
在SpringMvc中的配置如下：

@ApiModel(description = “群组”)
