Question

我是瓷砖概念的新手。我试图用弹簧的apache瓷砖。我使用UrlBasedViewResolver来渲染视图。问题是它在一个页面中多次渲染视图。我的错误是什么？

enter image description here

它只显示一次，但它显示有关，直到服务器抛出异常。下面是我的堆栈跟踪

下面是我的代码

TestController.java

@Controller
public class TestController {

    @RequestMapping("/hello")
    public ModelAndView helloWorld() {
        String message = "Hello World, Spring 3.0!";
        System.out.println(message);
        return new ModelAndView("hello", "message", message);
    }
}

APP-servlet.xml中

的hello.jsp

<%@ page isELIgnored="false" %>
<html>
<head>
    <title>Spring 3.0 MVC Series: Hello World</title>
</head>
<body>
    ${message}
</body>
</html>

Answer 1

错误在tiles.xml中，这里是

<definition name="hello" extends="base.definition">
        <put-attribute name="title" value="hello" />
        <put-attribute name="body" value="/WEB-INF/jsp/hello.jsp" />
</definition>

我不应该写<put-attribute name="title" value="hello" />，因为在hello.jsp中已添加了title。所以定义应该是这样的

<definition name="hello" extends="base.definition">
        <put-attribute name="body" value="/WEB-INF/jsp/hello.jsp" />
</definition>

apache tiles与spring mvc集成

TestController.java

APP-servlet.xml中

tiles.xml

layout.jsp

的hello.jsp
