欢迎文件在春天不使用html文件

Question

欢迎文件在春天不使用html文件

135*_*355 5 html spring jsp maven welcome-file

我在web.xml中提供了我的欢迎文件但是在运行应用程序时,它显示404错误 http://172.16.2.16:8080/sampletest/

这是一个春季应用程序.

web.xml中

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://xmlns.jcp.org/xml/ns/javaee"

    </welcome-file-list>

我正在使用eclipse luna,java 8,tomcat 8和maven框架.index.html文件直接位于webapp文件夹下,web.xml位于webapp/WEB-INF文件夹下. 如果我使用index.jsp而不是index.html,它就可以了.然后欢迎页面将加载使用http://172.16.2.16:8080/sampletest/

问题仅在于欢迎文件.否则弹簧配置正常. http://localhost:8080/sampletest/test/将从数据库加载数据.

尝试添加<mvc:default-servlet-handler/>dispatcher-servlet.xml.

详情请见此处.

Answer 2

您已将所有传入的请求映射到dispatcher此处,

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

所以你URL对应用程序的所有请求都在调度程序内,因为'/'映射了所有传入的请求.检查应用程序服务器日志中的堆栈跟踪

更新:

您收到以下警告,因为'/'模式没有处理程序,

警告:在DispatcherServlet中找不到带有URI [/ AccelFlow /]的HTTP请求的映射,其名称为"dispatcher"

您可以选择以下任一选项,

将带有"/"的URL映射到控制器
添加特定的URL模式弹簧调度员如.htm or .do如你所愿

修改你的web.xml,

<servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>*.htm</url-pattern>
    </servlet-mapping>

在你的控制器中,

@RequestMapping(value = "/test.htm", method = RequestMethod.GET)
public @ResponseBody Response display() throws Exception {
    accelFlowFacade.disaply();
    Response res = new Response();
    return res;
}
