**基本步骤：**

*  添加错误页面配置
 *  书写对应action处理映射
    
    ## 添加错误页面配置 ##

package com.ahut.config;
    
    import org.springframework.boot.context.embedded.ConfigurableEmbeddedServletContainer;
    import org.springframework.boot.context.embedded.EmbeddedServletContainerCustomizer;
    import org.springframework.boot.web.servlet.ErrorPage;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.http.HttpStatus;
    
    /** * * @ClassName: ErrorPageConfig * @Description: 配置错误页面 * @author cheng * @date 2018年4月3日 下午3:45:49 */
    @Configuration
    public class ErrorPageConfig { 
    
        @Bean
        public EmbeddedServletContainerCustomizer containerCustomizer() {
            return new EmbeddedServletContainerCustomizer() {
    
                @Override
                public void customize(ConfigurableEmbeddedServletContainer container) {
                    ErrorPage error400Page = new ErrorPage(HttpStatus.BAD_REQUEST, "/400.html");
                    ErrorPage error401Page = new ErrorPage(HttpStatus.UNAUTHORIZED, "/401.html");
                    ErrorPage error404Page = new ErrorPage(HttpStatus.NOT_FOUND, "/errorPage/404");
                    ErrorPage error500Page = new ErrorPage(HttpStatus.INTERNAL_SERVER_ERROR, "/500.html");
    
                    container.addErrorPages(error400Page, error401Page, error404Page, error500Page);
                }
            };
        }
    
    }

## 书写对应action处理映射 ##

package com.ahut.action;
    
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    import com.ahut.common.ApiResponse;
    
    /** * * @ClassName: ErrorPageAction * @Description: 错误页面控制器 * @author cheng * @date 2018年4月3日 下午3:48:18 */
    @Controller
    @RequestMapping(value = "/errorPage")
    public class ErrorPageAction { 
    
        /** * 日志管理 */
        private Logger log = LoggerFactory.getLogger(ErrorPageAction.class);
    
        /** * * @Title: notFound * @Description: 配置404 * @return */
        @RequestMapping(value = "/404")
        @ResponseBody
        public ApiResponse notFound() {
            log.warn("没有找到对应的信息");
            return ApiResponse.createFailResponse("没有找到对应的信息");
        }
    
    }

**其中ApiResponse为自定义实体**

package com.ahut.common;
    
    import java.io.Serializable;
    
    /** * * @ClassName: ApiResponse * @Description: api返回结果响应实体类 * @author cheng * @date 2018年4月3日 下午2:34:47 */
    public class ApiResponse implements Serializable { 
    
        /** * 序列化 */
        private static final long serialVersionUID = -5178560042946902578L;
        /** * 成功类型 */
        private static final String SUCCESS_TYPE = "SUCCESS";
        /** * 失败类型 */
        private static final String FAIL_TYPE = "FAIL";
        /** * 没有数据提示 */
        private static final String NO_DATA = "NO DATA";
        /** * 成功信息 */
        private static final String SUCCESS_MSG = "REQUEST SUCCESS";
        /** * 失败信息 */
        private static final String FAIL_MSG = "REQUEST FAIL";
        /** * 类型 */
        private String type;
        /** * 信息 */
        private String msg;
        /** * 数据 */
        private Object data;
    
        /** * 私有化构造方法 */
        private ApiResponse() {
        }
    
        /** * 重写toString */
        @Override
        public String toString() {
            return "ApiResponse [type=" + type + ", msg=" + msg + ", data=" + data + "]";
        }
    
        /** * * @Title: createSuccessResponse * @Description: 成功返回,包含信息和数据 * @param msg * @param data * @return */
        public static ApiResponse createSuccessResponse(String msg, Object data) {
            ApiResponse response = new ApiResponse();
            response.setType(SUCCESS_TYPE);
            response.setMsg(msg);
            response.setData(data);
            return response;
        }
    
        /** * * @Title: createSuccessResponse * @Description: 成功返回,只包含信息 * @param msg * @return */
        public static ApiResponse createSuccessResponse(String msg) {
            return createSuccessResponse(msg, NO_DATA);
        }
    
        /** * * @Title: createSuccessResponse * @Description: 成功返回,只包含数据 * @param data * @param clazz * @return */
        public static ApiResponse createSuccessResponse(Object data, Class<?> clazz) {
            return createSuccessResponse(SUCCESS_MSG, data);
        }
    
        /** * * @Title: createFailResponse * @Description: 失败返回,包含信息和数据 * @param msg * @param data * @return */
        public static ApiResponse createFailResponse(String msg, Object data) {
            ApiResponse response = new ApiResponse();
            response.setType(FAIL_TYPE);
            response.setMsg(msg);
            response.setData(data);
            return response;
        }
    
        /** * * @Title: createFailResponse * @Description: 失败返回,只包含信息 * @param msg * @return */
        public static ApiResponse createFailResponse(String msg) {
            return createFailResponse(msg, NO_DATA);
        }
    
        /** * * @Title: createFailResponse * @Description: 失败返回,只包含数据 * @param data * @param clazz * @return */
        public static ApiResponse createFailResponse(Object data, Class<?> clazz) {
            return createFailResponse(FAIL_MSG, data);
        }
    
        public String getType() {
            return type;
        }
    
        public void setType(String type) {
            this.type = type;
        }
    
        public String getMsg() {
            return msg;
        }
    
        public void setMsg(String msg) {
            this.msg = msg;
        }
    
        public Object getData() {
            return data;
        }
    
        public void setData(Object data) {
            this.data = data;
        }
    
    }
