paip.spring3 mvc servlet的配置以及使用最佳实践



1． Web.xml 1

2． springMVC.xml 2

1． mvcAction .mvcAction 2

2． Resin4 发动跟踪mvc maping 3

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"?>

<beans xmlns="http://www.springframework.org/schema/beans"

<mvc:default-servlet-handler/>

<mvc:annotation-driven />

<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...
