b) 使用到的Json工具类：
package com.chy.ssh.utils;
public class Json {
private boolean success = false; //操作是否成功
private String msg; //提示信息
private Object o; //其他信息
public boolean isSuccess() {
return success;
}
public void setSuccess(boolean success) {
this.success = success;
}
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}
public Object getO() {
return o;
}
public void setO(Object o) {
this.o = o;
}
}
c) UserDTO：
package com.chy.ssh.business.bean;
import java.io.Serializable;
@SuppressWarnings("serial")
public class UserDTO implements Serializable{
private int id;
private String userName;
private String passWord;
private String createTime;
private String updateTime;
public UserDTO() {
super();
}
public String getCreateTime() {
return createTime;
}
public void setCreateTime(String createTime) {
this.createTime = createTime;
}
public St
