代码展示:
controller层配置:
@Controller
public class UserController {
private UserService service = new UserServiceImpl();
@RequestMapping(value="/list",method=RequestMethod.GET)
public String list(Model model) throws Exception {
List<User> list = service.getAll();
model.addAttribute("list", list);
return "list";
}
}
web.xml配置:
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>
springmvc.xml的配置:
<context:component-scan base-package="cn.jzh"></context:component-scan>
<context:annotation-config conversion-service="dateConverter"></context:annotation-config>
<!-- 视图解析 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"></property>
<property name="prefix" value="/WEB-INF/view/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<!-- 配置转换器 -->
<bean id="dateConverter" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
<property name="converters">
<bean class="cn.jzh.converter.DateConverter"></bean>
</property>
</bean>
<!-- 静态放行 -->
<mvc:default-servlet-handler/>
jsp层,就这一句话:
<a href="list.action">用户列表</a>
发现直接测试接口:项目名+list.action是没用的直接报404的路径找不到
另外,最后跳转的/WEB-INF/view/list.jsp也是存在的
错误所在:
原来是springmvc.xml的配置文件配置错了,注解的映射和驱动错误的使用了context:annotation-config,应该使用的是mvc:annotation-driven
