SpringMvc4集成swagger2

添加Swagger2依赖

在pom.xml中加入Swagger2的依赖

<dependency>
            <groupId>io.springfoxgroupId>
            <artifactId>springfox-swagger2artifactId>
            <version>2.5.0version>
        dependency>
        <dependency>
            <groupId>io.springfoxgroupId>
            <artifactId>springfox-swagger-uiartifactId>
            <version>2.5.0version>
        dependency> 
        
        <dependency>
            <groupId>com.fasterxml.jackson.coregroupId>
            <artifactId>jackson-annotationsartifactId>
            <version>2.5.0version>
        dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.coregroupId>
            <artifactId>jackson-databindartifactId>
            <version>2.5.0version>
        dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.coregroupId>
            <artifactId>jackson-coreartifactId>
            <version>2.5.0version>
        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"})  
@Configuration
public 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")
@Controller
public 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 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 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 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 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”)
