this.getHibernateTemplate().update(user);执行了新增操作却没有执行修改操作
重点就是一行代码“this.getHibernateTemplate().update(user);” 为什么执行不了修改操作而执行的是新增操作 而且我以前同样的写法却可以执行修改操作
//Dao层的实现类
@Override
public boolean update(User user) {
// TODO Auto-generated method stub
this.getHibernateTemplate().update(user);
return true;
}
//Service层实现类
@Override
public boolean update(User user) {
// TODO Auto-generated method stub
return this.dao.update(user);
}
//Action层
public String update(){
boolean a = this.service.update(user);
if (a) {
return SUCCESS;
} else {
return ERROR;
}
}
//User实体类
package com.bochy.vo;
/**
* User entity. @author MyEclipse Persistence Tools
*/
public class User implements java.io.Serializable {
// Fields
private Integer UId;
private String UName;
private Integer UAge;
// Constructors
/** default constructor */
public User() {
}
/** minimal constructor */
public User(Integer UId) {
this.UId = UId;
}
/** full constructor */
public User(Integer UId, String UName, Integer UAge) {
this.UId = UId;
this.UName = UName;
this.UAge = UAge;
}
// Property accessors
public Integer getUId() {
return this.UId;
}
public void setUId(Integer UId) {
this.UId = UId;
}
public String getUName() {
return this.UName;
}
public void setUName(String UName) {
this.UName = UName;
}
public Integer getUAge() {
return this.UAge;
}
public void setUAge(Integer UAge) {
this.UAge = UAge;
}
}
