我正在使用Spring framework 3.1.3.RELEASE& amp;开发一个简单的Web应用程序。 MAVEN。除非我从web.xml中取出监听器
,否则我的应用程序将无法启动<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
Tomcat报告以下错误:
INFO: Deploying web application archive sampleapp.war
11/12/2012 3:45:03 PM org.apache.catalina.core.StandardContext start
SEVERE: Error listenerStart
11/12/2012 3:45:03 PM org.apache.catalina.core.StandardContext start
SEVERE: Context [/sampleapp] startup failed due to previous errors
我的WEB.XML如下所示:
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">
<display-name>EMS</display-name>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/*-context.xml</param-value>
</context-param>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
</welcome-file-list>
</web-app>
此时应用程序上下文文件为空:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd">
</beans>
以下是WEB-INF / lib
下的JAR文件eclipselink-2.4.0.jar
javax.persistence-2.0.0.jar
mysql-connector-java-5.1.21.jar
spring-context-3.1.3.RELEASE.jar
spring-core-3.1.3.RELEASE.jar
spring-web-3.1.3.RELEASE.jar
spring-webmvc-3.1.3.RELEASE.jar
以下是WEB-INF
下的文件application.properties
spring-context.xml
web.xml
我理解:
我做错了什么?
答案 0 :(得分:4)
以下是您的问题:将spring-context.xml
移至WEB-INF/classes
并按如下方式设置上下文参数:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-context.xml</param-value>
</context-param>
WEB-INF不在CLASSPATH中。

我分享duffmo的推理,只是想指出,如果你将配置更新为:
,你可以将应用程序上下文保留在WEB-INF目录中<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>WEB-INF/spring-context.xml</param-value>
</context-param>
这样,您的全局应用程序上下文与调度程序配置位于同一目录中。

问题是我的POM文件中缺少Spring Dependencies。我最初在POM中有以下依赖项
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${spring.version}</version>
</dependency>
我在tomcat logging.properties 上启用了调试,看到我收到了一个类ava.lang.NoClassDefFoundError ,因为我添加了依赖项(一次一个)ava .lang.NoClassDefFoundError不断变化,直到满足所有依赖关系。之后ContextLoaderListener启动正常。我添加的依赖项是:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-asm</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-expression</artifactId>
<version>${spring.version}</version>
</dependency>
<!-- required by Spring -->
<dependency>
<groupId>commons-logging</groupId>
<artifactId>commons-logging</artifactId>
<version>1.1.1</version>
</dependency>
