涉及到很多xml配置没写：只写具体实现的所有类
1、实体类
对应数据表SYS_SBGL,
主键是SBBM，主键是自动生成的uuid
数据表内容如下（有图有真相）：
package com.jinhetech.yogurt.sbgl.entity; import java.io.Serializable; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.Id; import javax.persistence.PrimaryKeyJoinColumn; import javax.persistence.SequenceGenerator; import javax.persistence.Table; import org.hibernate.annotations.GenericGenerator; import org.springframework.cache.annotation.Cacheable; @Entity @Table(name="SYS_SBGL") @PrimaryKeyJoinColumn(name = "SBBM") @Cacheable(value = "baseCache") public class Sbgl implements Serializable{ private static final long serialVersionUID = -1423899016746755470L; //@SequenceGenerator(name = "MY_SUQUENCE", sequenceName = "SEQ_SYS_SBGL") //@GeneratedValue(generator="MY_SUQUENCE") //@GeneratedValue(generator="system_uuid") //@GenericGenerator(name="system_uuid", strategy="uuid") @Id private String sbbm; private String sbmc; private String sblx; private String sssx; private String ssjd; private String azsj; private String azry; private String sbzt; private String sbjd; private String sbwd; private String wxlxr; private String wxlxdh; private String sbywxcs; private String jzpylyz; private String mqsbcyr; private String bzsm; public String getSbbm() { return sbbm; } public void setSbbm(String sbbm) { this.sbbm = sbbm; } public String getSbmc() { return sbmc; } public void setSbmc(String sbmc) { this.sbmc = sbmc; } public String getSblx() { return sblx; } public void setSblx(String sblx) { this.sblx = sblx; } public String getSssx() { return sssx; } public void setSssx(String sssx) { this.sssx = sssx; } public String getSsjd() { return ssjd; } public void setSsjd(String ssjd) { this.ssjd = ssjd; } public String getAzsj() { return azsj; } public void setAzsj(String azsj) { this.azsj = azsj; } public String getAzry() { return azry; } public void setAzry(String azry) { this.azry = azry; } public String getSbzt() { return sbzt; } public void setSbzt(String sbzt) { this.sbzt = sbzt; } public String getSbjd() { return sbjd; } public void setSbjd(String sbjd) { this.sbjd = sbjd; } public String getSbwd() { return sbwd; } public void setSbwd(String sbwd) { this.sbwd = sbwd; } public String getWxlxr() { return wxlxr; } public void setWxlxr(String wxlxr) { this.wxlxr = wxlxr; } public String getWxlxdh() { return wxlxdh; } public void setWxlxdh(String wxlxdh) { this.wxlxdh = wxlxdh; } public String getSbywxcs() { return sbywxcs; } public void setSbywxcs(String sbywxcs) { this.sbywxcs = sbywxcs; } public String getJzpylyz() { return jzpylyz; } public void setJzpylyz(String jzpylyz) { this.jzpylyz = jzpylyz; } public String getMqsbcyr() { return mqsbcyr; } public void setMqsbcyr(String mqsbcyr) { this.mqsbcyr = mqsbcyr; } public String getBzsm() { return bzsm; } public void setBzsm(String bzsm) { this.bzsm = bzsm; } }
2、JSP页面(sbgl_list.jsp)
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core_rt" %> <%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %> <%@ taglib prefix="shiro" uri="http://shiro.apache.org/tags" %> <!doctype html> <c:set var="ctx" value="${pageContext.request.contextPath}" scope="session"/> <html> <head> <title>设备管理</title> <!-- zTree需要的样式和js --> <link rel="stylesheet" href="${ctx }/yogurtResource/assembly/ztree/css/zTreeStyle.css" type="text/css"> <script type="text/javascript" src="${ctx }/yogurtResource/assembly/ztree/jquery.ztree.core-3.5.js"></script> <script type="text/javascript" src="${ctx }/yogurtResource/assembly/ztree/jquery.ztree.excheck-3.5.js"></script> <!-- 验证框架 --> <script type="text/javascript" src="${ctx }/yogurtResource/assembly/yogurt/user/formValidate.js"></script> <!-- 修改表单验证错误提示样式 --> <style type="text/css"> .table-bordered-ul li{ margin:0 5px;

var serActiveState = $('#ser_activeState').val(); var serOrgIds = $('#ser_orgId').val(); var serRoleIds = $('#ser_roleIds').val(); var attr = "?serUserName=" + encodeURI(encodeURI(serUserName)) + "&serActiveState=" + serActiveState + "&serOrgIds=" + serOrgIds + "&serRoleIds=" + serRoleIds; return "${ctx}/user/user_list" + attr; } </script> <!--分页结束--> </div> <!--分页end--> </body> </html>
3、Controller（SbglController.java）
@Controller("sbglController") @RequestMapping("/sbgl") public class SbglController extends BaseController { @Autowired private SbglDao dao; /** * 查询设备信息列表 * (在这里查询数据表所有数据，用Spring Data JPA框架自带的findAll()方法查询所有数据)。 */ @RequestMapping("sbgl_list") @RequiresRoles("sbgl/sbgl_list") public String getUserList(Model model) throws Exception {
//这两行就能查询到Sbgl类对应的数据表的所有数据库，并放在List集合里，供JSP页面调用 List<Sbgl> lst=new ArrayList<Sbgl>(); lst=(List<Sbgl>) dao.findAll(); System.out.println("aaa"); model.addAttribute("lst", lst); return "sbgl/sbgl_list"; } }
4、DAO层(Spring Data JPA只需要extends继承Spring Data JPA接口，不需要写SQL从数据表查询，上面提到的自带的findAll()方法就可以查到对应实体类数据表的所有数据 )
package com.jinhetech.yogurt.sbgl.dao; import org.springframework.data.jpa.repository.JpaSpecificationExecutor; import org.springframework.data.repository.CrudRepository; import org.springframework.data.repository.PagingAndSortingRepository; import org.springframework.stereotype.Repository; import com.jinhetech.yogurt.sbgl.entity.Sbgl; public interface SbglDao extends CrudRepository<Sbgl, String> { }
