篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Spring 4.2.2以上版本和swagger集成方案和踩过的坑相关的知识,希望对你有一定的参考价值。

因为公司使用的spring版本太高,在集成swagger的时候会存在一些问题,而网上的很多实例大多都是版本比较低的,为了是朋友们少才坑,我这边将集成的过程记录一下:

1. 引入spring、swagger的相关jar包(springfox-swagger2、springfox-swagger-ui),在pom.xml中配置:

提醒: 特别注意,springfox-swagger2在集成的时候,已经引入了spring的相关jar,特别是spring-context、spring-context-support的版本和项目中使用的版本完全不一致,项目在启动的时候出现很多包冲突的问题,这边在引入pom.xml文件的时候过滤掉了spring的相关jar包,如绿色标志。

 

2. 编写Swagger的配置类:

  1. package com.ml.honghu.swagger.web;  
  2.   
  3. import org.springframework.context.annotation.Bean;  
  4. import org.springframework.context.annotation.ComponentScan;  
  5. import org.springframework.context.annotation.Configuration;  
  6. import org.springframework.web.servlet.config.annotation.EnableWebMvc;  
  7.   
  8. import springfox.documentation.builders.ApiInfoBuilder;  
  9. import springfox.documentation.builders.PathSelectors;  
  10. import springfox.documentation.builders.RequestHandlerSelectors;  
  11. import springfox.documentation.service.ApiInfo;  
  12. import springfox.documentation.service.Contact;  
  13. import springfox.documentation.spi.DocumentationType;  
  14. import springfox.documentation.spring.web.plugins.Docket;  
  15. import springfox.documentation.swagger2.annotations.EnableSwagger2;  
  16.   
  17. @EnableWebMvc  
  18. @EnableSwagger2  
  19. @Configuration  
  20. @ComponentScan(basePackages ={"com.ml.honghu.**.rest"})  
  21. public class SwaggerConfig {  
  22.     @Bean  
  23.     public Docket createRestApi() {  
  24.         return new Docket(DocumentationType.SWAGGER_2)  
  25.                 .apiInfo(apiInfo())  
  26.                 .select()  
  27.                 .apis(RequestHandlerSelectors.basePackage("com.ml.honghu"))  
  28.                 .paths(PathSelectors.any())  
  29.                 .build();  
  30.     }  
  31.   
  32.     private ApiInfo apiInfo() {  
  33.         return new ApiInfoBuilder()  
  34.                 .title("接口列表 v1.0")  
  35.                 .description("接口信息")  
  36.                 .termsOfServiceUrl("http://honghu.com")  
  37.                 .contact(new Contact("", "", "HongHu"))  
  38.                 .version("1.1.0")  
  39.                 .build();  
  40.     }  
  41. }  
package com.ml.honghu.swagger.web;

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.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@EnableWebMvc
@EnableSwagger2
@Configuration
@ComponentScan(basePackages ={"com.ml.honghu.**.rest"})
public class SwaggerConfig {
	@Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.ml.honghu"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("接口列表 v1.0")
                .description("接口信息")
                .termsOfServiceUrl("http://honghu.com")
                .contact(new Contact("", "", "HongHu"))
                .version("1.1.0")
                .build();
    }
}

 提醒:注意红色标注的地方

 

 

3. 在spring-mvc.xml文件中进行过滤器的配置,过滤掉swagger的相关访问配置:

 

Java代码 技术分享 技术分享技术分享
  1. <mvc:exclude-mapping path="/swagger*/**"/>  
  2. <mvc:exclude-mapping path="/v2/**"/>  
  3. <mvc:exclude-mapping path="/webjars/**"/>  
<mvc:exclude-mapping path="/swagger*/**"/>
<mvc:exclude-mapping path="/v2/**"/>
<mvc:exclude-mapping path="/webjars/**"/>

 

 

4. 服务配置项

 

Java代码 技术分享 技术分享技术分享
  1. <span style="color: rgb(255, 0, 0);">@Api("区域服务")</span>  
  2. @RestController  
  3. @RequestMapping(value = "/rest/area")  
  4. public class AreaService  {  
  5.   
  6.     @Autowired  
  7.     private AreaService areaService;  
  8.       
  9.     <span style="color: rgb(255, 0, 0);">@ApiOperation(value = "区域列表", httpMethod = "GET", notes = "区域列表")</span>  
  10.     @IsLogin  
  11.     @ResponseBody  
  12.     @RequestMapping(value = "treeData", method = RequestMethod.GET)  
  13.     public List<Map<String, Object>> treeData(  
  14.             <span style="color: rgb(255, 0, 0);">@ApiParam(required = true, value = "区域ID")</span>  @RequestParam(required=false) String extId, HttpServletResponse response) {  
  15.         List<Map<String, Object>> mapList = Lists.newArrayList();  
  16.         List<Area> list = areaService.findAll();  
  17.         for (int i=0; i<list.size(); i++){  
  18.             Area e = list.get(i);  
  19.             if (StringUtils.isBlank(extId) || (extId!=null && !extId.equals(e.getId()) && e.getParentIds().indexOf(","+extId+",")==-1)){  
  20.                 Map<String, Object> map = Maps.newHashMap();  
  21.                 map.put("id", e.getId());  
  22.                 map.put("pId", e.getParentId());  
  23.                 map.put("name", e.getName());  
  24.                 mapList.add(map);  
  25.             }  
  26.         }  
  27.         return mapList;  
  28.     }  
  29. }  
@Api("区域服务")
@RestController
@RequestMapping(value = "/rest/area")
public class AreaService  {

	@Autowired
	private AreaService areaService;
	
	@ApiOperation(value = "区域列表", httpMethod = "GET", notes = "区域列表")
	@IsLogin
	@ResponseBody
	@RequestMapping(value = "treeData", method = RequestMethod.GET)
	public List<Map<String, Object>> treeData(
			@ApiParam(required = true, value = "区域ID")  @RequestParam(required=false) String extId, HttpServletResponse response) {
		List<Map<String, Object>> mapList = Lists.newArrayList();
		List<Area> list = areaService.findAll();
		for (int i=0; i<list.size(); i++){
			Area e = list.get(i);
			if (StringUtils.isBlank(extId) || (extId!=null && !extId.equals(e.getId()) && e.getParentIds().indexOf(","+extId+",")==-1)){
				Map<String, Object> map = Maps.newHashMap();
				map.put("id", e.getId());
				map.put("pId", e.getParentId());
				map.put("name", e.getName());
				mapList.add(map);
			}
		}
		return mapList;
	}
}
