spring3 + dwr 怎么能够配置成功
在网上搜了两三天了
发现自己总是配不成功
无数个报错信息
好不容易弄了个启动不报错的
可是这回执行的时候报空指针了
目前项目使用的是注解的方式进行操作的
分为按照MVC的模式进行包的划分
数据库用mybatis支持
打算被dwr暴露的类是一个service中的类
该类执行数据库操作时使用了用@Autowired的dao类进行数据库操作
现在需要增加dwr的功能
可是怎么样都配置不成功
有没有可以在这种状况下配置成功啊?
具体的配置说明如下(原有配置,不包含dwr的配置信息):
web-info目录下有system-servlet.xml和web.xml两个文件
以上配置都已经是正常的可以使用的
web.xml
<filter>
<filter-name>Set Character Encoding</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>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>Set Character Encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<servlet>
<servlet-name>system</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>system</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
