Answer 1

没找到servlet啊，看看struts的配置

Answer 2

struts配置：加一句，serverlet不是封装了吗？还要自己写？
<?xml version="1.0" encoding="UTF-8"?>

高手来顶啊。user.hbm.xml及bank.hbm.xml要怎么配置外键才不会出错。。...

Answer 4

看hibernate文档，里面有例子

Answer 5

问题解决了实体User必须定义Set中的属性banks
package com.sms.po;import java.util.HashSet;
import java.util.Set;public class User {
private  String name;
private  String pwd;
private Set banks=new HashSet();
public Set getBanks() {
return banks;
}
public void setBanks(Set banks) {
this.banks = banks;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPwd() {
return pwd;
}
public void setPwd(String pwd) {
this.pwd = pwd;
}}
Bank中也要定义User属性package com.sms.po;public class Bank {
private String count;
private String name;
private String balance;
private User user;
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public String getCount() {
return count;
}
public void setCount(String count) {
this.count = count;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getBalance() {
return balance;
}
public void setBalance(String balance) {
this.balance = balance;
}
}
