Java, Spring, Apache Tiles error : Could not resol

问题:

I'm new to Tiles and Spring MVC (I looked through several similar issues but found no solution for 'my problem')

controller:

@Controller
public class IndexController {

    @RequestMapping("/index")
    public String index(){
        return "index";
    }
}

My 'general.xml' containing the Tiles definitions:

<tiles-definitions>
<definition name="common" template="/WEB-INF/layout/classic.jsp">
    <put-attribute name="footer" value="/WEB-INF/layout/footer.jsp" />
</definition>

<definition name="index" extends="common">
    <put-attribute name="title" value="My First Application" />
    <put-attribute name="body" value="/WEB-INF/jsp/index.jsp" />
</definition>

exception:

回答1:

The problem is extremely simple. Replace your web.xml with

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
  <display-name>my-first-app</display-name>


  <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

        <load-on-startup>1</load-on-startup>
    </servlet>

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

I also added a jstl dependency to the pom

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
</dependency>

After these changes, a request to localhost:8080/index correctly renders the appropriate response

回答2:

The problem lies in the project location.

A combination of jetty, apache tiles and spring's view resolver does not work when there is a space in the location.

For ex : a project location - D:\folder whitespace\your_project will throw the above error -Could not resolve view with name 'index' in servlet with name 'dispatcher'

Solution - Please change your project location to a path with no space in it.

I've had the same issue today. I am also new at Spring so I didn't know where to start. After a long day I managed to find the answer:

My default.xml file was wrong. I had done some manual refactoring and that caused all the trouble. This is an example of what was wrong:

<definition name="tos.base" template="/WEB-INF/templates/default.jsp">
<put-attribute name="includes" value="" ></put-attribute>
<put-attribute name="title" value="Title" ></put-attribute>
<put-attribute name="header" value="/WEB-INF/tiles/header.jsp"></put-attribute>
<put-attribute name="content" value="/WEB-INF/tiles/content.jsp"></put-attribute>
<put-attribute name="footer" value="/WEB-INF/tiles/footer.jsp"></put-attribute>
</definition>

<definition name="home" extends="tos.base">
<put-attribute name="title" value="Homepage" ></put-attribute>
<put-attribute name="content" value="/WEB-INF/tiles/home.jsp"></put-attribute>
</definition>

<definition name="current" extends="to.base">
<put-attribute name="title" value="Current" ></put-attribute>
<put-attribute name="content" value="/WEB-INF/tiles/current.jsp"></put-attribute>
</definition>

As you can see I had the wrong value in the last definition "extends" value. I discovered this downgrading from tiles3.TilesViewResolver to tiles2.TilesViewResolver and that provided a more helpful error message.

回答4:

Try to change the return value of IndexController.index() from "/WEB-INF/jsp/index.jsp" to "index". This works for me:

@RequestMapping("/index")
public String index() {
    return "index";
}

回答5:

I've had the same issue . Try using correct version of DTD in tiles configuration file.

Also in your tiles definition file general.xml use tile:insertAttribute instead of tile:addAttribute

<tile:insertAttribute name="body"/>
     <br />
<tile:insertAttribute name="footer" />

There's probably a whitespace in your project's path:
