ssm框架最基本源码:
https://download.csdn.net/download/helloworld_in_java/10230214
eclipse下载:
默认的classpath是在工程的build文件夹中。可将classpath改为配置放在WEB-INF中。更改操作为: 右键工程 -> Build Path -> Configure Build Path-> 找到Source栏 -> 修改Default output folder为: ssmDemo/WebContent/WEB-INF/classes )
JavaWeb:报错信息The superclass “javax.servlet.http.HttpServlet” was not found on the Java Build Path
原因:
Javaweb工程类中没有添加Tomcat运行时相关类导致。
解决方法:
1、右击web工程-》属性或Build Path-》Java Build Path->Libraries-> Add Libray…->Server Runtime -》Tomcat Server
2、切换到Java Build Path界面中的Orader and Export,选择Tomcat。
eclipse编译报错:Access restriction: The type Resource is not accessible due to restriction on required library D:\Program Files\Java\jre6\lib\rt.jar
解决方法:
Project -> Properties -> libraries,先remove掉JRE System Library,然后再Add Library重新加入。
eclipse编译报错:The import java.util cannot be resolved
错误原因:
原因:
这是由于你的项目buildpath不对
解决方案:
右键项目-------buildpath--------Config Build Path最下面那个configuration 的选择libraries找到JRE(这个时候你会发现这个jre前面有!或者是红X)选中remove掉重新为该项目选择一个JRE选中项目,project----clean
spring-mvc.xml配置文件:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd"> <context:component-scan base-package="com.test.controller" /> <mvc:annotation-driven /> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> </beans>
Eclipse中设置编码的方式:
1、windows->Preferences…打开"首选项"对话框,左侧导航树,导航到 general->Workspace,右侧Text file encoding,选择Other,改变为UTF-8,以后新建立工程其属性对话框中的Text file encoding即为UTF-8。
2、windows->Preferences…打开"首选项"对话框,左侧导航树,导航到 general->Content Types,右侧Context Types树,点开Text,选择Java Source File,在下面的Default encoding输入框中输入UTF-8,点Update,则设置Java文件编码为UTF-8。其他java应用开发相关的文件 如:properties、XML等已经由Eclipse缺省指定,分别为ISO8859-1,UTF-8,如开发中确需改变编码格式则可以在此指定。
3、经过上述两步,新建java文件即为UTF-8编码,Eclipse编译、运 行、调试都没问题,但是做RCP应用的Product输出时、或者插件输出时,则总是出错,要么不能编译通过(输出时要重新compile)、要么输出的 插件运行时中文显示乱码。此时需要再RCP应用、或插件Plugin工程的build.properties中增加一 行,javacDefaultEncoding… = UTF-8。让输出时编译知道java源文件时UTF-8编码。这个设置需要保证所有的java源文件时UTF-8编码格式,如果不全是,可以参考 Eclipse帮中(Plug-in Development Environment Guide > Reference > Feature and Plug-in Build configuration),建议全部java源文件是UTF-8编码。

eclispe项目目录结构截图:
注意,这里的resources文件夹必须是Source Folder,而不是普通的Folder,不然web.xml会找不到该配置文件。
代码如下:
