Spring MVC是通过DispatcherServlet来加载Spring配置文件的，因此不需要在web.xml中配置ContextLoaderListener。但是CXF却需要通过ContextLoaderListener来加载Spring。
这样就产生了一个矛盾，如果不配置ContextLoaderListener，CXF就无法正常使用。但如果配置ContextLoaderListener，又会造成Spring的重复加载（DispatcherServlet一次，ContextLoaderListener一次） 在网上查了一下资料，只看到一个国外的程序员提出不配置ContextLoaderListener，通过写一个CXFController，来替代默认的CXFServlet。但是这种HACK的方式总是不太好 所以我采用一种折中的方式，来解决Spring MVC和cxf并存的问题。但是也不是很优雅，希望有人能给出更好的办法 首先是web.xml的配置
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="MyFramework" version="3.0">
<display-name>MyFramework</display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
WEB-INF/beans.xml,
WEB-INF/cxf.xml
</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<servlet>
<servlet-name>framework</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>WEB-INF/spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>framework</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>CXFServlet</servlet-name>
<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>CXFServlet</servlet-name>
<url-pattern>/webservice/*</url-pattern>
</servlet-mapping>
</web-app>
在ContextLoaderListener里面，加载cxf和spring的公共配置信息。然后在DispatcherServlet中加载spring mvc所需的信息。利用Spring配置文件拆分的方式，既实现spring mvc和cxf的共存，又避免spring配置信息的重复加载 然后是公共的配置信息，beans.xml
<?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:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="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
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.1.xsd">
<context:component-scan base-package="com.huawei.framework" />
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:jdbc.properties</value>
</list>
</property>
</bean>
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driver}" />
<property name="jdbcUrl" value="${jdbc.url}" />
<property name="user" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="minPoolSize" value="10" />
<property name="maxPoolSize" value="50" />
</bean>
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="mappingLocations"
value="classpath:/com/huawei/framework/model/**/*.hbm.xml" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
<prop key="hibernate.jdbc.fetch_size">50</prop>
<prop key="hibernate.jdbc.batch_size">25</prop>
<prop key="hibernate.temp.use_jdbc_metadata_defaults">false</prop>
</props>
</property>
</bean>
<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory" ref="sessionFactory" />
<property name="fetchSize" value="10" />
</bean>
<bean id="transactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<tx:annotation-driven transaction-manager="transactionManager" />
</beans>
然后是cxf所需的信息，cxf.xml
<?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:jaxws="http://cxf.apache.org/jaxws"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://cxf.apache.org/jaxws
http://cxf.apache.org/schemas/jaxws.xsd">
<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
<jaxws:endpoint id="helloWorld"
implementorClass="com.huawei.framework.webservice.HelloWorldImpl"
address="/HelloWorld" />
</beans>
最后是spring mvc所需的信息，spring-mvc.xml
<?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/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
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">
<context:component-scan base-package="com.huawei.framework" />
<mvc:annotation-driven />
<mvc:default-servlet-handler />
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver"
p:prefix="/WEB-INF/view/" p:suffix=".jsp"
p:viewClass="org.springframework.web.servlet.view.JstlView" />
</beans>
这顺便还带来一个附带的好处，即进行单元测试的时候，可以仅加载必须的类，比如做DAO组件的单元测试，就不需要加载spring-mvc.xml和cxf.xml了
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "file:WebContent/WEB-INF/beans.xml" })
public class UserDaoHibernateTest {
@Autowired
private UserDao dao;
private static String ID;
@Test
public void testInsert() {
User user = new User();
user.setName("fme001");
user.setAge(23);
dao.insert(user);
}
@Test
public void testQueryByName() {
String name = "fme001";
User user = dao.queryByName(name);
assertEquals(23, user.getAge());
ID = user.getId();
}
@Test
public void testQueryByAge() {
int age = 23;
List<User> result = dao.queryByAge(age);
assertEquals(1, result.size());
}
@Test
public void testQueryAll() {
List<User> result = dao.queryAll();
assertEquals(1, result.size());
}
@Test
public void testQuery() {
User user = dao.query(ID);
assertEquals(23, user.getAge());
assertEquals("fme001", user.getName());
}
@Test
public void testUpdate() {
User user = dao.query(ID);
user.setAge(24);
dao.update(user);
user = dao.query(ID);
assertEquals(24, user.getAge());
}
@Test
public void testDelete() {
User user = dao.query(ID);
dao.delete(user);
}
}
可以看到，集成cxf和spring mvc确实不算很方便，需要绕一绕。上述方法只是一个折中的方案，希望新版本的cxf可以提供一个CXFController，这样的话就可以统一用DispatcherServlet来加载Spring，不配置ContextLoaderListener。这样的话web.xml可以简洁很多。或者如果哪位网友有更好的方式，请指教一下 声明：ITeye文章版权属于作者，受法律保护。没有作者书面许可不得转载。
