Spring 4.2.2以上版本和swagger集成方案和踩過的坑

因爲公司使用的spring版本太高，在集成swagger的時候會存在一些問題，而網上的很多實例大多都是版本比較低的，爲了是朋友們少才坑，我這邊將集成的過程記錄一下：

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

Xml代碼

io.springfox

springfox-swagger2

2.4.0

org.springframework

spring-core

org.springframework

spring-beans

org.springframework

spring-context

org.springframework

spring-context-support

org.springframework

spring-aop

org.springframework

spring-tx

org.springframework

spring-orm

org.springframework

spring-jdbc

org.springframework

spring-web

org.springframework

spring-webmvc

org.springframework

spring-oxm

io.springfox

springfox-swagger-ui

2.4.0

io.springfox

springfox-swagger2

2.4.0

org.springframework

spring-core

org.springframework

spring-beans

org.springframework

spring-context

org.springframework

spring-context-support

org.springframework

spring-aop

org.springframework

spring-tx

org.springframework

spring-orm

org.springframework

spring-jdbc

org.springframework

spring-web

org.springframework

spring-webmvc

org.springframework

spring-oxm

io.springfox

springfox-swagger-ui

2.4.0

提醒： 特別注意，springfox-swagger2在集成的時候，已經引入了spring的相關jar，特別是spring-context、spring-context-support的版本和項目中使用的版本完全不一致，項目在啓動的時候出現很多包衝突的問題，這邊在引入pom.xml文件的時候過濾掉了spring的相關jar包，如綠色標誌。

2. 編寫Swagger的配置類：

Java代碼

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"})

publicclass SwaggerConfig {

@Bean

public Docket createRestApi() {

returnnew Docket(DocumentationType.SWAGGER_2)

.apiInfo(apiInfo())

.select()

.apis(RequestHandlerSelectors.basePackage("com.ml.honghu"))

.paths(PathSelectors.any())

.build();

}

private ApiInfo apiInfo() {

returnnew 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：注意紅色標註的地方

3. 在spring-mvc.xml文件中進行過濾器的配置，過濾掉swagger的相關訪問配置：

Java代碼

4. 服務配置項

Java代碼

@Api("區域服務")

@RestController

@RequestMapping(value ="/rest/area")

publicclass AreaService  {

@Autowired

private AreaService areaService;

@ApiOperation(value ="區域列表", httpMethod ="GET", notes ="區域列表")

@IsLogin

@ResponseBody

@RequestMapping(value ="treeData", method = RequestMethod.GET)

public List> treeData(

@ApiParam(required =true, value ="區域ID")@RequestParam(required=false) String extId, HttpServletResponse response) {

List> mapList = Lists.newArrayList();

List list = areaService.findAll();

for (int i=0; i

Area e = list.get(i);

if (StringUtils.isBlank(extId) || (extId!=null && !extId.equals(e.getId()) && e.getParentIds().indexOf(","+extId+",")==-1)){

Map map = Maps.newHashMap();

map.put("id", e.getId());

map.put("pId", e.getParentId());

map.put("name", e.getName());

mapList.add(map);

}

}

return mapList;

}

}

@Api("區域服務")

@RestController

@RequestMapping(value = "/rest/area")

public class AreaService  {

@Autowired

private AreaService areaService;

@ApiOperation(value = "區域列表", httpMethod = "GET", notes = "區域列表")

@IsLogin

@ResponseBody

@RequestMapping(value = "treeData", method = RequestMethod.GET)

public List> treeData(

@ApiParam(required = true, value = "區域ID")  @RequestParam(required=false) String extId, HttpServletResponse response) {

List> mapList = Lists.newArrayList();

List list = areaService.findAll();

for (int i=0; i

Area e = list.get(i);

if (StringUtils.isBlank(extId) || (extId!=null && !extId.equals(e.getId()) && e.getParentIds().indexOf(","+extId+",")==-1)){

Map map = Maps.newHashMap();

map.put("id", e.getId());

map.put("pId", e.getParentId());

map.put("name", e.getName());

mapList.add(map);

}

}

return mapList;

}

}
