ExtJS下 Ext.Direct加载和提交过程排错小结

偶泪滴嘎嘎，终于，终于完成了一部分ExtJS。
（基础夯实一点，会有好处的，排错的时候就体现出来了）
下面就Ext.Direct做一些排错笔记：

错误一：

这是为什么呢？
答案：
@DirectFormPostMethod
这个不对，这个产生了上面的错误，改成： @DirectMethod
同时删掉，由@DirectFormPostMethod生成的输出：

复制代码代码如下:

import com.softwarementors.extjs.djn.config.annotations.DirectFormPostMethod;

错误二：

复制代码代码如下:

控制层出错，也就是逻辑上不对，我的函数里面要求传入的参数，和提交的参数不对，
放心，不是xml配置问题，是传入的参数问题。所以重点在参数上，也就是语法。

我的错误原因：
Java要求传入的参数为两个：

复制代码代码如下:

public Info submitData(String name,String password)

而我在ExtJS 中实际传入的参数是一个：

复制代码代码如下:

 
var params= username.getValue()+Password.getValue(); 
FormAction.submitData(params,function(result,e){} 

改写一下就行了：

复制代码代码如下:

 
FormAction.submitData(username.getValue(),Password.getValue(),function(result,e){} 

错误三：

复制代码代码如下:

原因是里面没有这个类：
com.softwarementors.extjs.djn.test.config.GsonBuilderConfiguratorForTesting
这个错误在web.xml里面，把它们删了就行了：

复制代码代码如下:

 
registryConfiguratorClass 
com.softwarementors.extjs.djn.test.servlet.config.RegistryConfiguratorForTesting  
 
gsonBuilderConfiguratorClass 
com.softwarementors.extjs.djn.test.config.GsonBuilderConfiguratorForTesting
