MyEclipse環境的項目改爲在Eclipse中運行爬坑記

新檢出一個web項目，同事都是運行在MyEclipse中的，我用Eclipse啓動，

 

1、首先是許多jar包報錯：

處理方法爲 remove掉，然後 選 WEB-INF 下的所有 jar 重新添加進去。

 

2、MyEclipse 中自帶 JavaEE5 library jar包合集，而Eclipse中沒有，項目中有用到，解決方法

從同事的 MyEclipse 安裝目錄下把  EE_5 目錄拷過來，主要是有下面這4個jar包：

然後，添加到項目中，可以建一個用戶目錄：

 

 

這樣就建好了，如圖：

但是這時，項目啓動，還是不會把這些jar引入到項目中，還需要如下配置：

添加完是如下效果：

 

這樣就把Javaee5的相關jar包徹底引入到項目中了。

 

3、啓動項目，報如下異常：

 

典型異常信息： URL [jar:file:/C:/Program%20Files%20(x86)/Java/jre6/lib/ext/jfxrt.jar!/com/sun/glass/ui/Accessible.class

 

全部異常信息如下：

 不管是 使用 jdk 1.8，還是jdk 1.6 都是報上面的異常。

 最終參考下面的博文，

org.springframework.asm.ClassReader.(Unknown Source) 解決方案

此類問題一般在 spring版本 與 jdk版本不匹配的情況下會出現。

匹配規則：

spring3 + java7

spring4 + java8

解決方案：

 

1：檢查項目的jdk編譯版本 ：右鍵項目，進入項目偏好設置，找到 java Compiler ，將jdk修改到你對應的spring版本

2：檢查tomcat的jre版本：以eclipse爲例：打開eclipse的偏好設置，搜索 server ，找到 Runtime Environments 找到你加載進來的tomcat 點擊edit,將jre修改爲對應你spring的版本。

到此問題應該就能得到解決。

 

 

發現本地項目用的Spring是3.1：

 

 將jdk改爲1.7後，故障排除【奇怪的是，同時用MyEclipse，用的其自帶1.6環境運行項目居然不報錯】。

 

 

Eclipse切換jdk的方法：

一、Eclipse中整體添加多個jdk

 

 

這裏只要選中一個包含 jdk 內容的目錄即可，這個目錄中的jdk不用真的安裝在電腦裏面，只要有這個文件夾就行了。

這樣一個新的 jdk環境就添加到Eclipse中了，一個Eclipse中可以添加多個JDK環境。

 

二、項目的JDK主要有兩個部分

1編譯環境：

項目右鍵

 

2、是運行項目的Tomcat的jdk環境:
