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:
- <dependency>
- <groupId>io.springfox</groupId>
- <artifactId>springfox-swagger2</artifactId>
- <version>2.4.0</version>
- <exclusions>
- <exclusion>
- <groupId>org.springframework</groupId>
- <artifactId>spring-core</artifactId>
- </exclusion>
- <exclusion>
- <groupId>org.springframework</groupId>
- <artifactId>spring-beans</artifactId>
- </exclusion>
- <exclusion>
- <groupId>org.springframework</groupId>
- <artifactId>spring-context</artifactId>
- </exclusion>
- <exclusion>
- <groupId>org.springframework</groupId>
- <artifactId>spring-context-support</artifactId>
- </exclusion>
- <exclusion>
- <groupId>org.springframework</groupId>
- <artifactId>spring-aop</artifactId>
- </exclusion>
- <exclusion>
- <groupId>org.springframework</groupId>
- <artifactId>spring-tx</artifactId>
- </exclusion>
- <exclusion>
- <groupId>org.springframework</groupId>
- <artifactId>spring-orm</artifactId>
- </exclusion>
- <exclusion>
- <groupId>org.springframework</groupId>
- <artifactId>spring-jdbc</artifactId>
- </exclusion>
- <exclusion>
- <groupId>org.springframework</groupId>
- <artifactId>spring-web</artifactId>
- </exclusion>
- <exclusion>
- <groupId>org.springframework</groupId>
- <artifactId>spring-webmvc</artifactId>
- </exclusion>
- <exclusion>
- <groupId>org.springframework</groupId>
- <artifactId>spring-oxm</artifactId>
- </exclusion>
- </exclusions>
- </dependency>
- <dependency>
- <groupId>io.springfox</groupId>
- <artifactId>springfox-swagger-ui</artifactId>
- <version>2.4.0</version>
- </dependency>
<dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>2.4.0</version> <exclusions> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> </exclusion> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> </exclusion> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> </exclusion> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> </exclusion> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> </exclusion> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> </exclusion> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> </exclusion> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> </exclusion> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> </exclusion> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> </exclusion> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring-oxm</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>2.4.0</version> </dependency>
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:
- 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();
- }
- }
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:
- <mvc:exclude-mapping path="/swagger*/**"/>
- <mvc:exclude-mapping path="/v2/**"/>
- <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
- <span style="color: rgb(255, 0, 0);">@Api("区域服务")</span>
- @RestController
- @RequestMapping(value = "/rest/area")
- public class AreaService {
- @Autowired
- private AreaService areaService;
- <span style="color: rgb(255, 0, 0);">@ApiOperation(value = "区域列表", httpMethod = "GET", notes = "区域列表")</span>
- @IsLogin
- @ResponseBody
- @RequestMapping(value = "treeData", method = RequestMethod.GET)
- public List<Map<String, Object>> treeData(
- <span style="color: rgb(255, 0, 0);">@ApiParam(required = true, value = "区域ID")</span> @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;
- }
- }
@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; } }
