paip.spring3 mvc servlet的配置以及使用最佳实践
3． No mapping found for HTTP request with URI 3
1．Web.xml
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/springMVC.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name> <!-- 这里在配成spring,下边也要写一个名为spring-servlet.xml的文件，主要用来配置它的controller -->
<url-pattern>*.json</url-pattern>
</servlet-mapping>
Xml的位置可以放得个多个地张儿..不过mvc还是放得个web-inf哈面儿好,不用铜布xml...减少部署的问题..
多个文件/WEB-INF/xxx/*.xml
classpath*:/springMVC.xml

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

<mvc:default-servlet-handler/>

<context:annotation-config />
<context:component-scan base-package="comapi.**,com.im"/>
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
</beans>
1．mvcAction .mvcAction
@Controller
@RequestMapping("/im") 这个参数也能不代了...
public class mvcAction {
@RequestMapping(value = "/list3")
public void searchByKeyword2(String idxf, String keyword, int offset,
int limit, HttpServletResponse response) throws Exception {
response.getWriter().write("json txt");
}
2．Resin4 发动跟踪mvc maping
发动resin的时候儿,能看见所有的生成的map url 了....feobye调试...
3． No mapping found for HTTP request with URI
这个问题是更改孪注解的Url...但是,resin不reload....
只要更改class,biru添加一个方法,就能reload兰...生效兰...
