没有映射的DispatcherServlet发现HTTP请求的URI具有与Thymeleaf和Spring 4

Question

我想春天4 Thymeleaf整合，但我得到了

WARNING [http-apr-8080-exec-4] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/hire-platform/] in DispatcherServlet with name 'mvc-dispatcher' 

，而不是显示的内容/WEB-INF/templates/index.html。这里是mvc-dispatcher-servlet-xml：

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
    xmlns:p="http://www.springframework.org/schema/p" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd" 
> 

<bean 
    id="viewResolver" 
    class="org.thymeleaf.spring4.view.ThymeleafViewResolver" 
    p:templateEngine-ref="templateEngine" 
    p:characterEncoding="UTF-8" 
> 
</bean> 

<bean 
    id="servletContext" 
    class="beans.ServletContextFactory" 
></bean> 

<bean 
    id="templateResolver" 
    class="org.thymeleaf.templateresolver.ServletContextTemplateResolver" 
    p:prefix="/WEB-INF/templates/" 
    p:suffix=".html" 
    p:templateMode="HTML5" 
> 
    <constructor-arg ref="servletContext"/> 
</bean> 
<bean 
    id="templateEngine" 
    class="org.thymeleaf.spring4.SpringTemplateEngine" 
    p:templateResolver-ref="templateResolver" 
> 
</bean> 

凡servletContext豆完全从How to set ServletContext property for a bean in Spring XML metadata configuration answer复制粘贴，需要为构造函数的参数，因为我在我刚才的问题，Failed to instantiate [org.thymeleaf.templateresolver.ServletContextTemplateResolver]: No default constructor found发现。我认为它应该重定向到HTML文件（index.html），当我使用JSP（index.jsp）而不是Thymeleaf时，它工作。也许我在applicationContext.xml文件中缺少一些东西？下面是applicationContext.xml文件的外观：

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jdbc="http://www.springframework.org/schema/jdbc" 
    xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" 
    xmlns:aop="http://www.springframework.org/schema/aop" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd 
     http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd 
     http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd 
     http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd 
    "> 

<jdbc:embedded-database id="DataSource" type="HSQL"> 
</jdbc:embedded-database> 

<context:component-scan base-package="beans"/> 

<bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager"> 
    <property name="sessionFactory" ref="SessionFactory"></property> 
</bean> 

<tx:annotation-driven /> 

我删除Spring AOP部分，SessionFactory豆和<!--<mvc:annotation-driven/>-->评论，因为我觉得这里是不需要的。 我已经包含在pom.xml从Maven的Thymeleaf依赖：

<!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api --> 
<dependency> 
    <groupId>javax.servlet</groupId> 
    <artifactId>javax.servlet-api</artifactId> 
    <version>4.0.0-b01</version> 
</dependency> 

<!-- https://mvnrepository.com/artifact/org.thymeleaf/thymeleaf --> 
<dependency> 
    <groupId>org.thymeleaf</groupId> 
    <artifactId>thymeleaf</artifactId> 
    <version>3.0.0.RELEASE</version> 
</dependency> 
<!-- https://mvnrepository.com/artifact/org.thymeleaf/thymeleaf-spring4 --> 
<dependency> 
    <groupId>org.thymeleaf</groupId> 
    <artifactId>thymeleaf-spring4</artifactId> 
    <version>3.0.0.RELEASE</version> 
</dependency> 

所以，我敢肯定，我失去了一些东西简单，像一个配置行。如果有人愿意帮助我，我将不胜感激，谢谢。 P.S. 我还包括web.xml文件，因为我看到了类似的问题有它：

<!DOCTYPE web-app PUBLIC 
     "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" 
     "http://java.sun.com/dtd/web-app_2_3.dtd" > 

<web-app> 
    <display-name>Archetype Created Web Application</display-name> 

    <context-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value>/WEB-INF/applicationContext.xml</param-value> 
    </context-param> 

    <!-- The Bootstrap listener to start up and shut down Spring's root WebApplicationContext. It is registered to Servlet Container --> 
    <listener> 
    <listener-class> 
     org.springframework.web.context.ContextLoaderListener 
    </listener-class> 
    </listener> 
    <listener> 
    <listener-class> 
     org.springframework.web.context.request.RequestContextListener 
    </listener-class> 
    </listener> 

    <servlet> 
    <servlet-name>mvc-dispatcher</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
    <load-on-startup>1</load-on-startup> 
    </servlet> 

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

我也尝试添加控制器：

@Controller 
public final class MainController { 
    @RequestMapping(value = "/") 
    public String displayFirstView() { 
     return "index.html"; 
    } 
} 

但它并没有帮助。 解决方案：我错过了中的<mvc:annotation-driven/>，我必须为第一个视图设置一个控制器（如我在这里包含的MainController）。感谢那些帮助我解决这个问题的用户。

Answer 1

你缺少这读取@Controller注释需要<mvc:annotation-driven/>。尝试添加它。

Answer 2

从我可以从下面的链接看到，你的viewResolver应该引用templateEngine。
