一：项目使用springboot集成swagger进行调试，配置swagger非常简单，主要有三步：
1、添加swagger依赖
<!-- 引入 swagger等相关依赖 --> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>2.6.1</version> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>2.6.1</version> </dependency>2、进行swagger的配置
package com.sailing.springbootmybatis.config; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import springfox.documentation.builders.ApiInfoBuilder; import springfox.documentation.builders.PathSelectors; 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; /** * @author baibing * @project: springboot-mybatis * @package: com.sailing.springbootmybatis.config * @Description: swagger2配置类 * @date 2018/9/25 15：35 */ @Configuration @EnableSwagger2 public class Swagger2Config { @Bean public Docket createRestApi(){ return new Docket(DocumentationType.SWAGGER_2) .apiInfo(apiInfo()) .select() .apis(RequestHandlerSelectors.basePackage("com.sailing.springbootmybatis.controller")) .paths(PathSelectors.any()) .build(); } private ApiInfo apiInfo(){ return new ApiInfoBuilder() .title("SPRING-BOOT整合MYBATIS--API说明文档") .description("2018-8完成版本") .contact("Sailing西安研发中心-baibing") .version("1.0") .license("署名-非商用-相同方式共享 4.0转载请保留原文链接及作者") .licenseUrl("https://creativecommons.org/licenses/by-nc-sa/4.0/") .build(); } }3、在controller层添加相应的注解（@Api和@ApiOperation 以及@ApiIgnore等）
package com.sailing.springbootmybatis.controller; import com.sailing.springbootmybatis.bean.Userinfo; import com.sailing.springbootmybatis.common.log.LogOperationEnum; import com.sailing.springbootmybatis.common.log.annotation.MyLog; import com.sailing.springbootmybatis.common.response.BuildResponseUtil; import com.sailing.springbootmybatis.common.response.ResponseData; import com.sailing.springbootmybatis.common.websocket.WebSocketServer; import com.sailing.springbootmybatis.service.RedisService; import com.sailing.springbootmybatis.service.UserinfoService; import io.swagger.annotations.Api; import io.swagger.annotations.ApiOperation; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.validation.BindingResult; import org.springframework.web.bind.annotation.*; import springfox.documentation.annotations.ApiIgnore; import javax.validation.Valid; import java.io.IOException; import java.util.List; /** * @author baibing * @project: springboot-mybatis * @package: com.sailing.springbootmybatis.controller * @Description: Userinfo controller 控制层 * @date 2018/9/12 10:07 */ @RestController @Api(value = "USERINFO", description = "用户信息测试controller") public class UserinfoController{ @Autowired private UserinfoService userinfoService; @Autowired private WebSocketServer webSocketServer; @Autowired private RedisService redisService; /** * 查找指定id对应的用户 * @param id * @return */ @RequestMapping(value = "/user/{id}", method = RequestMethod.GET) @MyLog(type = LogOperationEnum.SELECT,value = "查询指定id的用户信息") @ApiOperation(value = "查询指定id的用户信息接口", notes = "查询指定id的用户信息接口") public ResponseData getUser(@PathVariable(value = "id") Integer id){ return userinfoService.findById(id); } /** * 查找所有用户 * @return */ @RequestMapping(value = "/users", method = RequestMethod.GET) @MyLog(type = LogOperationEnum.SELECT,value = "查询全部用户信息") @ApiOperation(value = "查询所有用户信息接口", notes = "查询所有用户信息接口") public ResponseData getAllUsers(){ return userinfoService.findAllUsers(); } /** * 查找所有用户（带分页） * @param page 当前页数 * @param rows 每页显示条数 * @return */ @RequestMapping(value = "/users/p", method = RequestMethod.GET) @ApiOperation(value = "查询所有用户信息接口(带分页)", notes = "查询所有用户信息接口(带分页)") public ResponseData getAllUsers(Integer page, Integer rows){ return userinfoService.findAllUsers(page, rows); } /** * 新增用户 (带参数校验@Valid) * 注意：BindingResult 对象必须在 @Valid 的紧挨着的后面，否则接收不到错误信息 * @Valid 可以校验json 也可以校验表单传递的对象属性 * @param userinfo * @return */ @RequestMapping(value = "/user", method = RequestMethod.POST) @MyLog(type = LogOperationEnum.INSERT, value = "新增用户信息") @ApiOperation(value = "新增用户接口(包含参数校验)", notes = "新增用户接口(包含参数校验)") public ResponseData saveUserinfo(@RequestBody @Valid Userinfo userinfo, BindingResult bindingResult){ if(bindingResult.hasErrors()){ return BuildResponseUtil.buildFailResponse(bindingResult.getFieldError().getDefaultMessage()); } return userinfoService.saveUser(userinfo); } /** * 删除指定用户 * @param id 用户id * @return */ @RequestMapping(value = "/user/{id}", method = RequestMethod.DELETE) @ApiOperation(value = "删除指定id的用户信息接口", notes = "删除指定id的用户信息接口") public ResponseData deleteUser(@PathVariable Integer id){ return userinfoService.deleteUser(id); } /** * 更新用户 * @param userinfo * @return */ @RequestMapping(value = "/user", method = RequestMethod.PUT) @ApiOperation(value = "更新指定id用户信息接口", notes = "更新指定id用户信息接口") public ResponseData updateUserinfo(@RequestBody Userinfo userinfo){ return userinfoService.updateUser(userinfo); } /** * 给指定用户推送消息 * @param userName 用户名 * @param message 消息 * @throws IOException */ @RequestMapping(value = "/socket", method = RequestMethod.GET) @ApiIgnore //使用此注解忽略方法的暴露，也可以用在controller上 @ApiOperation(value = "给指定用户推送socket消息接口", notes = "给指定用户推送socket消息接口") public void testSocket(@RequestParam String userName,@RequestParam String message){ webSocketServer.sendInfo(userName, message); } /** * 测试redis接口保存String类型action * @param address * @return */ @RequestMapping(value = "/redis", method = RequestMethod.POST) @ApiIgnore //使用此注解忽略方法的暴露，也可以用在controller上 @ApiOperation(value = "redis中添加String数据接口", notes = "redis中添加String数据接口") public ResponseData setString(@RequestBody String address){ System.out.println(address); return redisService.setValue(address); } /** * 测试redis接口保存实体类型action * @param userinfo * @return */ @RequestMapping(value = "/redis/userinfo", method = RequestMethod.POST) @ApiIgnore //使用此注解忽略方法的暴露，也可以用在controller上 @ApiOperation(value = "redis中添加Userinfo实体接口", notes = "redis中添加Userinfo实体接口") public ResponseData setEntity(@RequestBody Userinfo userinfo){ return redisService.setEntityValue(userinfo); } /** * 测试redis接口读取实体类型action * @param key * @return */ @RequestMapping(value = "/redis/userinfo/{key}", method = RequestMethod.GET) @ApiIgnore //使用此注解忽略方法的暴露，也可以用在controller上 @ApiOperation(value = "redis中读取指定key对应的数据接口", notes = "redis中读取指定key对应的数据接口") public ResponseData getEntity(@PathVariable String key){ return redisService.getEntityValue(key); } /** * * @param list * @return */ @RequestMapping(value = "/redis/userList", method = RequestMethod.POST) @ApiIgnore //使用此注解忽略方法的暴露，也可以用在controller上 @ApiOperation(value = "redis中添加包含Userinfo实体的集合接口", notes = "redis中添加包含Userinfo实体的集合接口") public ResponseData setCollection(@RequestBody List<Userinfo> list){ return redisService.setCollectionValue(list); } /** * 测试redis接口读取实体类型action * @param key * @return */ @RequestMapping(value = "/redis/userList/{key}", method = RequestMethod.GET) @ApiOperation(value = "redis中读取指定key对应的集合数据接口", notes = "redis中读取指定key对应的集合数据接口") public ResponseData getCollection(@PathVariable String key){ return redisService.getCollectionValue(key); } }二：到这里配置就结束了，访问http://127.0.0.1:端口/项目路径/swagger-ui.html 就ok了， 页面如下：
三：项目运行了一段时间后访问上面连接突然报404错误，百思不得其解，但是可以肯定的是加了什么配置导致，最后在application.yml中发现了一个配置：
spring.mvv.resources.add-mapping:false将其注释掉熟悉的界面又回来了，查阅资料发现这个配置是不自动给静态资源添加路径，导致swagger-ui.html找不到资源，知道原因后摸索看能不能在保留以上配置的前提下自己手动给swagger-ui.html添加静态资源路径呢？
package com.sailing.springbootmybatis.config; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry; import org.springframework.web.servlet.config.annotation.ViewControllerRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; /** * 在SpringBoot2.0及Spring 5.0 WebMvcConfigurerAdapter已被废弃，目前找到解决方案就有 * 1 直接实现WebMvcConfigurer （官方推荐） * 2 直接继承WebMvcConfigurationSupport * @ https://blog.csdn.net/lenkvin/article/details/79482205 */ @Configuration public class WebMvcConfig extends WebMvcConfigurerAdapter { @Override public void addResourceHandlers(ResourceHandlerRegistry registry) { registry.addResourceHandler("swagger-ui.html") .addResourceLocations("classpath:/META-INF/resources/"); registry.addResourceHandler("/webjars/**") .addResourceLocations("classpath:/META-INF/resources/webjars/"); } }发现通过以上代码手动给swagger-ui.html指定路径也可以解决404的问题。
