注解：实现EmpBizImpl的bean类

1.EmpBizImpl—一个bean类

package biz.impl;import java.sql.SQLException;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.stereotype.Repository;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Propagation;import org.springframework.transaction.annotation.Transactional;import biz.EmpBiz;import dao.DeptDao;import dao.EmpDao;import entity.Emp;@Service("empBiz")public class EmpBizImpl implements EmpBiz {    @Autowired    @Qualifier("edi")    private EmpDao edi;    private DeptDao deptDao;    public EmpBizImpl() {        super();    }    public EmpDao getEdi() {        return edi;    }    public void setEdi(EmpDao edi, DeptDao deptDao) {        this.edi = edi;        this.deptDao = deptDao;    }    public EmpBizImpl(EmpDao edi) {        super();        this.edi = edi;    }    @Override    @Transactional(readOnly=true)    public List<Emp> findAllEmp() {        return edi.findAllEmp();    }    @Override    @Transactional(readOnly=true)    public List<Emp> findEmpByCondition(Emp e) {        // TODO Auto-generated method stub        return edi.findEmpByCondition(e);    }    @Override       @Transactional(readOnly=true)    public List<Emp> findEmpByNameParam(Emp e) {        // TODO Auto-generated method stub        return null;    }    @Override    @Transactional(readOnly=true)    public List<Emp> findEmpByExemple(Emp e) {        // TODO Auto-generated method stub        return null;    }    @Override    @Transactional(readOnly=true)    public Emp findEmpById(int id) {        // TODO Auto-generated method stub        return null;    }    @Override    @Transactional(propagation=Propagation.REQUIRED,rollbackFor={SQLException.class})    public int addEmp(Emp e) {        return edi.addEmp(e);    }    @Override    @Transactional(propagation=Propagation.REQUIRED,rollbackFor={SQLException.class})    public void modifyEmp(Emp e) {        edi.modify(e);    }    @Override    @Transactional(readOnly=true)    public List<Emp> findEmpbyPage(int pageNo, int pageSize) {        // TODO Auto-generated method stub        return edi.findEmpByPage(pageNo, pageSize);    }    @Override    @Transactional(propagation=Propagation.REQUIRED,rollbackFor={SQLException.class})    public void updateBatchEmpSal(double sal) {        edi.updateBatchEmpSal(sal);    }}
