解决方法为升级
|
1 2 3 4 5 |
<dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId> <version>${apache.commons.version}</version> </dependency> |
到更高的版本，如下：
|
1 2 |
<struts2.version>2.5.20</struts2.version> <apache.commons.version>3.8.1</apache.commons.version> |

升级Struts2之后报告HTTP Status 500 - java.lang.ClassNotFoundException: org.apache.jsp.index_jsp以及org.apache.jasper.JasperException: Unable to compile class for JSP
升级Struts2从2.3.20.1版本升级到2.5.5版本后可能报告如下错误：

也有可能发生如下错误信息：
|
1 |
HTTP Status 500 - java.lang.ClassNotFoundException: org.apache.jsp.index_jsp |
具体信息如下图：
比较诡异的是，在Tomcat 8的环境下，是可以正常运行的，但是在Tomcat 7环境下却会报错。造成这个现象的原因就是在引入的Jar包中包含了jsp-api.jar这个Jar包，只要在最后生成的war包中排除这个文件即可。
Spring Junit 读取WEB-INF下的配置文件
假设spring配置文件为applicationContext.xml
一.Spring配置文件在类路径下面
在Spring的Java应用程序中，一般我们的Spring的配置文件都是放在放在类路径下面(也即编译后会进入到classes目录下)。
以下是我的项目，因为是用maven管理的，所以配置文件都放在"src/main/resources"目录下,这时候，在代码中可以通过
|
1 |
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml"); |
然后获取相应的bean。
如果代码想用Junit测试框架来测试，则Spring提供了对Junit支持，还可以使用注解的方式：
|
1 2 |
@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations={"classpath:applicationContext.xml"}) |
只需要在相应的Test类前面加上此两个注解（第二个注解用来指明Spring的配置文件位置），就可以在Junit Test类使用中Spring提供的依赖注入功能。
二.Spring配置文件在WEB-INF下面
当然在做J2EE开发时，有些人习惯把Spring文件放在WEB-INF目录（虽然更多人习惯放在类路径下面）下面,或者有些Spring配置文件是放在类路径下面，而有些又放在WEB-INF目录下面，如下图:
这时候，在代码中就不可以使用ClassPathXmlApplicationContext来加载配置文件了，而应使用FileSystemXmlApplicationContext。
|
1 |
ApplicationContext applicationContext = new FileSystemXmlApplicationContext("src/main/webapp/WEB-INF/applicationContext.xml"); |
然后获取相应的bean。
如果代码想用Junit测试框架来测试，则Spring提供了对Junit支持，还可以使用注解的方式：
|
1 2 |
@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations={"file:src/main/webapp/WEB-INF/applicationContext.xml"}) |
只需要在相应的Test类前面加上此两个注解（第二个注解用来指明Spring的配置文件位置），就可以在Junit Test类使用中Spring提供的依赖注入功能。
下面是我的一个Spring管理下的Junit测试类：
