我正在遵循与本 404 Error - Java Spring MVC using Maven in Eclipse from Tutorial 中相同的教程填写表格后出现 404 错误

源项目
那么如何才能在填完表单后成功得到“display.jsp”页面。
最佳答案
您在 telusko-servlet.xml 中缺少 InternalResourceViewResolver bean
<!-- Define Spring MVC view resolver -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/view/" />
<property name="suffix" value=".jsp" />
</bean>
将 jsp 页面放在 WEB-INF/view 文件夹中而不是放在外面也是一个很好的做法。 添加该 bean 后，您不会返回 显示.jsp
你的 Controller 方法应该是这样的
@RequestMapping("/add")
public String add() {
return "display";
}
如果上面没有帮助尝试使用像这样的东西，那么避免在你的 bean xml 中使用版本也是明智的
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
