用struts2 + hibernate写一个登陆 遇到点问题!

Question

如题.
这是我的类"WorkServ.java"package com.msger.workserv;import com.msger.factory.Factory;
import com.opensymphony.xwork2.ActionSupport;
@SuppressWarnings("serial")
public class workServ extends ActionSupport{
private Integer usersId;
    private String usersNumber;
    private String usersName;
    private String usersPass;

public String doLogin(){
String flag = SUCCESS;
System.out.println(usersName);
try {
if(Factory.getServiceInstence().doLogin(usersName, usersPass)){
flag = SUCCESS;
}else{
flag = ERROR;
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

return flag;
} public Integer getUsersId() {
return usersId;
} public void setUsersId(Integer usersId) {
this.usersId = usersId;
} public String getUsersNumber() {
return usersNumber;
} public void setUsersNumber(String usersNumber) {
this.usersNumber = usersNumber;
} public String getUsersName() {
return usersName;
} public void setUsersName(String usersName) {
this.usersName = usersName;
} public String getUsersPass() {
return usersPass;
} public void setUsersPass(String usersPass) {
this.usersPass = usersPass;
}
}页面通过action,跳到这个类,
问题是:我写个主方法运行doLogin()就能够查找到信息.
而且如果我将if(Factory.getServiceInstence().doLogin(usersName, usersPass)){删掉
也能够跳转到正确页面,而且经过确定 usersName 在此是有作用的 :-(
放到
可是换到浏览器点击按钮提交就报错↓HTTP Status 500 -type Exception reportmessagedescription The server encountered an internal error () that prevented it from fulfilling this request.exceptionjava.lang.reflect.InvocationTargetException

Answer 2

以下是doLogin()方法public boolean doLogin(String usersName, String usersPass) throws Exception {
boolean flag = false;
try {
String hql = "from Users where usersName = :usersName and usersPass = :usersPass";
Query query = session.createQuery(hql);
query.setString("usersName", usersName);
query.setString("usersPass", usersPass);
Users users = (Users) query.uniqueResult();
if (users != null) {
flag = true;
} else {
flag = false;
}
} catch (Exception ex) {
System.out.println(ex);
}
return flag;

Answer 3

以下 是 登陆页面<form action="workserv/wordServLogin" method="post">
     登录名<input width="200px" type="text" name="UsersName" class="input"/><br/>
     密&nbsp;&nbsp;码<input width="200px" type="password" name="UsersPass" class="input"/><br/>
     <input type="submit" value=" 登 录 " class="btn"/>
     </form>

Answer 4

一般是包冲突的问题，好像是antl包有冲突

Answer 5

先把表单中的UsersName,UsersPass 改成usersName,usersPass 试试..不行的话,检查antl包是否冲突.

Answer 6

很同意，Struts2框架是根据get以及set判定的，变量名开头都要小写。

Answer 7

不明白楼主到底问题是什么！
如果仅仅是针对异常的话：struts包里面有也有个antlr_XXX.jar,与hibernate包里面的冲突了。在项目属性里把java build path里，把类库的位子调整了一下，把hibernate库调到最上面去就ok了。
针对方法的话：
方法一：
public String doLogin(){
        String flag = SUCCESS;
        System.out.println(usersName);
        try {
            if(Factory.getServiceInstence().doLogin(usersName, usersPass)){
                flag = SUCCESS;
            }else{
                flag = ERROR;
            }
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        
        return flag;
    }方法二：
public boolean doLogin(String usersName, String usersPass) throws Exception {
        boolean flag = false;
        try {
            String hql = "from Users where usersName = :usersName and usersPass = :usersPass";
            Query query = session.createQuery(hql);
            query.setString("usersName", usersName);
            query.setString("usersPass", usersPass);
            Users users = (Users) query.uniqueResult();
            if (users != null) {
                flag = true;
            } else {
                flag = false;
            }
        } catch (Exception ex) {
            System.out.println(ex);
        }
        return flag;
楼主为什么要判断两次呢？而且方法一中，方法名public String doLogin(){}和调用的方法名Factory.getServiceInstence().doLogin(usersName, usersPass)为什么要一样呢，我不知道具体有没有影响，不过，楼主应该自己斟酌自己的代码规范度，十分混乱感觉!
