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）：

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> {

}
