添加dtd文件
Window => Preferences => XML XML Catalog => add
例如mybatis-config.xml文件的文件頭如下：
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
在Eclipse中應(yīng)該設(shè)置：
將class文件輸出到指定文件夾
Project=>Properties=>Java Build Path=>Source=>Browser...
這樣做的用途：
在eclipse中默認(rèn)輸出的class實在bin目錄下的，但是在默認(rèn)情況下穆刻，tomcat會在WEB-INF/classes這個目錄下查找class文件，而不是在bin目錄下查找。通過更改class文件的輸出路徑到WEB-INF/classes這樣的操作胜嗓，我們可以把web應(yīng)用方便地部署到tomcat。
顯示空包或web/WEB-INF下的classes文件夾
Navigate=>Show In=>Navigator <=> Alt+Shift+W
看看效果钩乍，呦吼~
將已經(jīng)存在的項目載入eclipse中時出現(xiàn)No projects are found to import
原因：
工程項目的個目錄下面沒有.project和.classpath這兩個文件
解決：
- 建一個項目辞州，這個項目的項目名要import的項目名稱一樣；
- 新建的項目目錄里面有上述的兩個文件件蚕，把上述兩個文件拷到你要import的項目目錄下面孙技；
- 刪除之前建的那個項目产禾，然后再重新import。
修改Eclipse的編碼格式
Window=>Preferences=>Work Space
導(dǎo)入Maven項目：The declared package "com.myself" does not match the expected package "main.java.com.myself"
Set my-project/src/main/java as the source folder (Project => Properties => Java Build Path => Project => Add Folder). Remove the old source folder.
Restart eclipse if necessary.
Simply put, Eclipse thinks that your project begins at my-project/src. Therefore, it expects all packages to descend from there, starting with main.java.
問題解決來自：stackoverflow
The tomcat server configuration at /sever/tomcat v7.0 localhost-config is missing
原因：做項目時用的tomcat的版本/路徑和現(xiàn)在用 不一樣牵啦，tomcat版本或者路徑問題亚情。
解決：更改項目的tomcat或者路徑版本方法。
項目右擊=>run as=>run on server=> manually define a new server
No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?
- On your Eclipse IDE, go into
Window>Preferences>Java>Installed JREs> and check yourinstalled JREs. You should have an entry with a JDK there. - Select the Execution Env as show below. Click
OK - Then
Right-Clickon your Project ->Maven->Update Project
Additionally, you may have to change Maven JRE which is as follows. Goto Run -> Run Configurations, selecting the Maven Build I was running (from the left panel). Then, I clicked the JRE tab and selected the option Workspace default JRE
