小弟初学Spring mvc ，Url,不能请求Controller
Java
@Controller
@RequestMapping("/crm/ext")
public class TestExtController {
    private IJdbcService jdbcService;
    @Autowired
public void setJdbcService(IJdbcService jdbcService) {
this.jdbcService = jdbcService;
}
    @RequestMapping("listJson.do")
public String listJson(String s_name,int start,int limit,
HttpServletRequest request, HttpServletResponse response)throws Exception {
String sql = "select * from C_test t";
if(StringUtil.isNotBlank(s_name)){
sql += " where t.UNAME like '"+s_name+"%'";
}
Map mapls = jdbcService.queryPage(start, limit, sql);

JSONObject jsonResult = new JSONObject();
jsonResult.put("dblist", mapls.get("dblist"));
jsonResult.put("total", mapls.get("count"));
ServletsUtil.writeHtml(response, jsonResult.toString());
return null;
}

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/spring-servlet.xml</param-value>
    </init-param>
    <load-on-startup>4</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>*.do</url-pattern>
</servlet-mapping>

spring-servlet.xml

    <context:annotation-config />

    
    <context:component-scan base-package="com.hc.crm.web">
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"></context:include-filter>
    </context:component-scan>

    
    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

    
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/page/" p:suffix=".jsp" />

jsp
var store = Ext.create('Ext.data.Store', {
            fields:[{name: 'UNAME'},{name: 'EMAIL'},{name: 'PHONE'},{name: 'ADDR'},{name: 'TEL'},{name: 'CY'},{name: 'SFZ'},{name: 'CSD'},{name: 'CSNY'}],
                pageSize: 20, //页容量20条数据
                remoteSort: false,
                remoteFilter: true,
                 proxy: {
                  type: 'ajax',
url: '/crm/test/listJson.doajax=true&',
          reader: {
                     type: 'json',
                     root: 'dblist',
                     totalProperty: 'total'
                   }
                },
