进销存管理系统的功能需求：
1，实现采购订单的持久化，对采购商品入库处理，还有就是采购的退货处理；
2，实现商品的入库、出库操作，查询商品的库存信息，修改商品的仓库号
3，实现销售订单的添加，销售发货处理，并且销售的退货处理
4，实现新建员工培训信息和查询员工培训记录功能
5，实现对商品、供应商、客户资料的管理，对员工用户的管理，最重要的是对系统数据的备份和恢复

bean层manage的代码如下所示：
package com.xu.bean; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.Table; import org.springframework.stereotype.Component; /** * * @author 公众号：springmeng *管理员 *id:管理员编号 *name:管理员名字 *password:登录密码 *gender:性别 *age:年龄 *phone number:手机号码 *deptId:部门id */ @Entity @Table(name = "managers") @Component public class Managers { @Id @GeneratedValue(strategy=GenerationType.AUTO) @Column(name="managers_id") private Long id; @Column(name="managers_name") private String name; @Column(name="managers_password") private String password; @Column(name="managers_gender") private String gender; @Column(name="managers_age") private Long age; @Column(name="managers_phonenumber") private String phonenumber; /*@ManyToOne(cascade=CascadeType.ALL,fetch=FetchType.LAZY,optional=false,targetEntity=Dept.class) @JoinColumn(name="dept_name") private String deptName;*/ public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getGender() { return gender; } public void setGender(String gender) { this.gender = gender; } public String getPhonenumber() { return phonenumber; } public void setPhonenumber(String phonenumber) { this.phonenumber = phonenumber; } public Long getAge() { return age; } public void setAge(Long age) { this.age = age; } /*public String getDeptName() { return deptName; } public void setDeptName(String deptName) { this.deptName = deptName; }*/ }
dao层MessageRepository的代码如下所示：
package com.xu.dao; import org.springframework.data.jpa.repository.JpaRepository; import org.springframework.data.jpa.repository.Modifying; import org.springframework.data.jpa.repository.Query; import org.springframework.transaction.annotation.Transactional; import com.xu.bean.Message; public interface MessageRepository extends JpaRepository<Message, Long>{ @Query("select count(id) from Message where flag = '未查看'") public Long findConts(); @Transactional @Modifying(clearAutomatically = true) @Query(value ="update message set flag='已查看' where id=?1",nativeQuery=true) public void updateMessageById(Long id); }
Mananger的代码如下所示：
