springmvc4+springmvc4+hibernate4事务问题（全部都是用注解）

异常信息如下：

org.springframework.dao.InvalidDataAccessApiUsageException: Write operations are not allowed in read-only mode (FlushMode.MANUAL):Turn your Session into FlushMode.COMMIT/AUTO or remove 'readOnly' marker from transaction definition.at org.springframework.orm.hibernate4.HibernateTemplate.checkWriteOperationAllowed(HibernateTemplate.java:1135)

这种情况下是spring配置文件和springmvc配置文件分开进行配置的（下面还有在一个文件中进行配置的情况）。异常信息比较简单，保存的时候没有添加事务，所以添加时事务是处于read only状态的，无法进行保存，就报了这个异常，但是仔细查看了代码以及配置，事务相关的东西似乎都是完好的，没有问题，对这个问题比较纠结。

后经高人指点。有些眉目

第一种解决方案：

我在spring和springmvc中的配置文件中都有这么一句配置

<context:component-scan base-package="com.h3c.itac" />

在spring中该配置需要改为：

<context:component-scan base-package="com.h3c.itac" ><context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>   </context:component-scan>

意思为在spring配置启动的时候不去扫描Controller
在springmvc中该配置改为：

<context:component-scan base-package="com.h3c.itac" ><context:exclude-filter type="annotation" expression="......"/>   <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>   </context:component-scan>

springmvc中的这个配置exculde的记不清是什么了，exculde和inculde是有先后顺序的，具体谁先谁后可以去实验一下。

第二种解决方案：

在dao层调用HibernateTemplate的execute方法，不要使用save，如下

 public void saveSyslogAlarm(SyslogAlarm s){    this.getHibernateTemplate().execute(new HibernateCallback<T>() {}) }

第三种解决方案：

只使用一种配置文件，也就是说只使用springmvc的配置文件（如果只使用spring配置文件是不行的，因为在配置springmvc前端控制器DispatcherServlet的时候，会去默认的路径下寻找名为action-servlet.xml的文件,/WEB-INF/action-servlet.xml)。

web.xml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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"id="WebApp_ID" version="3.0"><display-name>SpringHibernateJsfTest</display-name><!-- 加载顺序 content-param -> listener -> filter -> servlet --><!-- <context-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/config/spring/applicationContext.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener> -->   <filter><filter-name>encode</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>utf-8</param-value></init-param></filter><filter-mapping><filter-name>encode</filter-name><url-pattern>/*</url-pattern></filter-mapping><servlet><servlet-name>springServlet</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/config/spring/servlet-context.xml</param-value></init-param><load-on-startup>1</load-on-startup><async-supported>true</async-supported></servlet><servlet-mapping><servlet-name>springServlet</servlet-name><url-pattern>/</url-pattern></servlet-mapping><welcome-file-list><welcome-file>index.html</welcome-file><welcome-file>index.htm</welcome-file><welcome-file>index.jsp</welcome-file><welcome-file>default.html</welcome-file><welcome-file>default.htm</welcome-file><welcome-file>default.jsp</welcome-file></welcome-file-list></web-app>
