问题描述
我想将Spring 4与Thymeleaf集成，但我得到了：
I want to integrate Spring 4 with Thymeleaf, but I got:

我找到了这个主题：，但我使用的是Maven，我对Thymeleaf-Spring4和Thymeleaf本身有依赖关系：
I found this topic: Error creating bean with name 'templateResolver', but I am using Maven and I have dependencies for Thymeleaf-Spring4 and Thymeleaf itself:
<!-- 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>
我在 mvc-dispatcher-servlent.xml中创建bean 像这样：
<bean
id="viewResolver"
class="org.thymeleaf.spring4.view.ThymeleafViewResolver"
>
</bean>
<bean
id="templateResolver"
class="org.thymeleaf.templateresolver.ServletContextTemplateResolver"
>
</bean>
<bean
id="templateEngine"
class="org.thymeleaf.spring4.SpringTemplateEngine"
p:templateResolver-ref="templateResolver"
>
</bean>
在IntelliJ IDEA 2016.2 EAP中也发生了一些奇怪的事情我认为，因为我已经完成了缺失的 org.thymeleaf.templateresolver.ServletContextTemplateResolver 。有人看到我犯的错误吗？提前感谢您的每一个答案。
我找到了一个解决方案，因为解析器在构造函数中需要一个参数，我必须创建 ServletContextFactory （如）并将其注入解析器的构造函数：
Also something weird happened in IntelliJ IDEA 2016.2 EAP I think, because I have completion for missing org.thymeleaf.templateresolver.ServletContextTemplateResolver. Does anybody see mistake I make? Thank you in advance for every answer.I found a solution, because resolver needs an argument in constructor, I have to create ServletContextFactory (as in How to set ServletContext property for a bean in Spring XML metadata configuration) and inject it to resolver's constructor:
<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>
推荐答案
您需要挂钩 templateEngine 到 viewResolver 。这是我的工作：
You will need to hook in your templateEngine to the viewResolver. Here's my working one:
<bean id="viewResolver" class="org.thymeleaf.spring4.view.ThymeleafViewResolver">
<property name="order" value="1"/>
<property name="characterEncoding" value="UTF-8"/>
<property name="templateEngine" ref="templateEngine"/> <!-- THIS -->
</bean>
<bean id="templateEngine" class="org.thymeleaf.spring4.SpringTemplateEngine">
<property name="templateResolvers">
<set>
<ref bean="webTemplateResolver"/>
</set>
</property>
<property name="additionalDialects">
<set>
<bean class="org.thymeleaf.extras.springsecurity4.dialect.SpringSecurityDialect"/>
</set>
</property>
</bean>
