Answer 1

呵呵，谢谢……哎，想Spring插件安装上重新搭建SSH框架可是在线安装老是失败！
我这个Eclipse是eclipse-jee-indigo-win32.zip
用的迷迷糊糊的，懊恼啊！自己顶一下！

Answer 2

即使是手动写，总要搭框架要写配置文件，
那么我还是要建applicationContext.xml还是要自己写里面的内容，有意义吗？？？

Answer 3

是不是两个ide的jdk版本不一样

Answer 4

你的applicationContext配置你的action了没？

Answer 5

还是一个个copy吧 这样比较保险

Answer 6

现在的错误就是Action里面调用方法的mat为NullPointerException也就是我的SessionFactory注入失败！

Answer 7

有些奇怪，为什么我的applicationContext.xml文件没有叶子呢（一般这个文件前不都是一片叶子）莫非我放在src下，放错位置了！！！可是Myeclipse下面就是这样放的

Answer 8

检查是否少了jar包，或者java文件没有编译，可以看classpath下是否有class文件

Answer 9

eclipse中我实在不知道到哪里找classpath,创建项目的时候默认的是build可是打开却是空……

Answer 10

好吧，下面是我的错误信息！（图片不能显示，大家就将就一下吧）
// 查询所有自动售货机
public String getAllAutomat(){
System.out.println("action mat:");
System.out.println(mat==null);
try{
List list=mat.findAll("Automat");(这里是29行)
automats=getPageResult(list);
}catch(Exception e){
e.printStackTrace();
}

return "index";
}
异常如下：
action mat:
true
java.lang.NullPointerException

Answer 11

要是哪位对eclipse比较熟悉的话，帮我远程协助一下也行啊！QQ：156003025

Answer 12

看一下你的jdk和tomcat是多少版本的。我需要知道。

Answer 13

我先导入了一个web项目： struts2的mvc模式，运行成功了！这样就表示我的eclipse-jee-indigo-win32.zip tomcat6.0.33  jdk6.0是可以协同工作的ok？

Answer 14

现在我不知道我的SSH2框架是不是在eclipse里面不能用啊！

Answer 15

mat是我定义的一个接口，没错就是mat注入失败！找不到原因啊！我现在就是怀疑我在eclipse里面的SSH框架applicationContext放得有问题，可是……

Answer 16

你的项目大吗？可以发一份给我吗？[email protected]

Answer 17

楼主System.out.println(mat==null);
你这一句有问题。

Answer 18

你看一下System.out.println(mat==null);
这句代码

Answer 19

System.out.println(mat==null);我这句怎么了？？？（项目虽小，但jar包太多，挺慢的！）

Answer 20

问题解决了，还是我项目转换问题！详见：http://blog.csdn.net/lvhongfen/article/details/6763180
