Spring MVC和Spring Data JPA之获取数据表数据放在List集合，显示在JSP页面

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)

</div>

<!--分页-->

return "${ctx}/user/user_list" + attr;
}

<!--分页结束-->

<!--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> {

}
