SSH2整合的问题

有爱的小止 2012-04-21 10:37:37
这些全是MyEclipse里导的

spring 我是导入了Spring 2.0 AOP , Core , Persistence Core和web libraries

然后hibernate导的是core和advanced support包

然后struts2导的是struts core 和 struts-spring-plugin包

还有另外的两个 commons-pool.jar 和 commons-dbcp.jar


之后配置了一个web.xml文件如下


<?xml version="1.0" encoding="UTF-8"?>

<web-app version="3.0" 

	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">

<display-name></display-name>	

 <context-param> 

	<param-name>contextConfigLocation</param-name> 

	<param-value>/WEB-INF/classes/applicationContext.xml</param-value>

</context-param> 



	<listener>

		<listener-class>

			org.springframework.web.context.ContextLoaderListener

		</listener-class>

	</listener>

	

  <welcome-file-list>

    <welcome-file>index.jsp</welcome-file>

  </welcome-file-list>

  <filter>

  	<filter-name>struts2</filter-name>

  	<filter-class>

  		org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

  	</filter-class>

  </filter>

  <filter-mapping>

  	<filter-name>struts2</filter-name>

  	<url-pattern>/*</url-pattern>

  </filter-mapping>

  </web-app>



applicationContext.xml的文件内容如下


<?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"

	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">





	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">

		<property name="driverClassName" value="com.mysql.jdbc.Driver">

		</property>

		<property name="url" value="jdbc:mysql://localhost:3306/ssh2test">

		</property>

		<property name="username" value="root"></property>

		<property name="password" value="123456"></property>

	</bean>

	<bean id="sessionFactory"

		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

		<property name="dataSource">

			<ref bean="dataSource" />

		</property>

		<property name="mappingResources">

		<list>

		<value>User.hbm.xml</value>

		</list>

		</property>

		<property name="hibernateProperties">

			<props>

				<prop key="hibernate.dialect">

					org.hibernate.dialect.MySQLDialect

				</prop>

			</props>

		</property>

	</bean>

</beans>



然后还有一个User.hbm.xml


<?xml version="1.0" encoding="utf-8"?>

<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<!-- 

    Mapping file autogenerated by MyEclipse Persistence Tools

-->

<hibernate-mapping package="com.zjj.util">

    <class name="User" table="user" catalog="demo">

        <id name="id" type="java.lang.Integer">

            <column name="id" />

            <generator class="increment"></generator>

        </id>

        <property name="userName" type="java.lang.String">

            <column name="userName" length="20" />

        </property>

        <property name="password" type="java.lang.String">

            <column name="password" length="20" />

        </property>

    </class>

</hibernate-mapping>



又写了一个简单的User.java文件 只有id userName 和 password

然后发布运行启动Tomcat服务器的时候报错 错误信息如下文

[Quote=引用 5 楼 new_sara 的回复:]

Hibernate 包中asm.jar 与Spring中asm-2.2.2.jar 冲突。删除 asm.jar
[/Quote]
我一般删除的是高版本的，当然如果你的问题是这个问题的话

检查Myeclipse帮你导入的jar包。

struts2必须JAR包（6个）：
struts2-spring-plugin-2.0.11.2.jar
xwork-2.0.5.jar
struts2-core-2.0.11.2.jar
freemarker-2.3.8.jar
ognl-2.6.11.jar
commons-logging-1.0.4.jar(与hibernate3.2必须JAR包重复，取一个既可)

hibernate3.2必须JAR包（8个）：
antlr-2.7.6.jar
commons-collections-2.1.1.jar
commons-logging-1.0.4.jar
dom4j-1.6.1.jar
ehcache-1.2.3.jar
hibernate3.jar
jta.jar
log4j-1.2.11.jar

spring2.5必须JAR包（5个）：
spring.jar
asm-2.2.2.jar (*)
asm-commons-2.2.2.jar (*)
asm-util-2.2.2.jar (*)
cglib-nodep-2.1_3.jar (*)

以上四个标*的jar包，hibernate,spring都有提供，但是一定要用spring下的，不然当部署到tomcat下，就会包那个错。你试试

好像说是内存溢出，不知道问题出在哪里了，各位大神帮我找找。。

网上找的好像有说是包冲突的，现在也不知道是哪个包冲突，内存太小不应该，项目里面什么东西都还没有写，不知道错误原因在哪里了。。
