Question

我正在尝试使用数据表的Spring MVC 4来发布前端数据。

我的项目名称是NewEDXUI。

情景： - index.jsp将从Controller / Rest Controller获取数据，以表格格式从数据库发布数据。

我面临的问题 - 我创建了web.xml和servlet.xml

1＆GT;在我的jsp中，如果我从资源文件夹中提供Js文件的路径 - 那么在加载时它正在寻找http://localhost:8080/NewEDXUI/Views/resources/js/client.js 如果不是＆＃34; resources / js / client.js＆＃34;我使用＆＃34; ../ resources / js / client.js＆＃34;然后正确加载client.js文件。

2 - ; Jsp页面有id =＆＃34; tableClient＆＃34;它应该从client.js var tableClient获取数据，这是在控制器包MainController.java中调用getAllPartners服务定义 ..但是当它正在调用时我正在接受获取http://localhost:8080/NewEDXUI/Views/getAllPartners?_=1497263560865 404（未找到）

请提供一些指导如何解决这些问题并完成我的第一个Spring项目。

项目结构

Web.xml中

<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
                         http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0" metadata-complete="true">
<display-name>Archetype Created Web Application</display-name>
<servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>
<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

用SpringMVC-servlet.xml中

Answer 1

为什么你使用Spring 4和xml文件配置？有关最佳实践，请在Spring 4上使用注释Config。
