Не удалось создать экземпляр [org.thymeleaf.templateresolver.ServletContextTemplateResolver]: конструктор по умолчанию не найден

Question

Я хочу интегрировать Spring 4 с Thymeleaf, но я получил:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'templateResolver' defined in ServletContext resource [/WEB-INF/mvc-dispatcher-servlet.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.thymeleaf.templateresolver.ServletContextTemplateResolver]: No default constructor found; nested exception is java.lang.NoSuchMethodException: org.thymeleaf.templateresolver.ServletContextTemplateResolver.<init>()

Я нашел эту тему: Error creating bean with name 'templateResolver', но я с использованием Maven и у меня есть зависимости для Thymeleaf-Spring4 и сам Thymeleaf:

<!-- 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> 

Я создаю фасоль в mvc-dispatcher-servlent.xml так:

<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> 

Также было что-то странное в IntelliJ IDEA 2016.2 EAP Я думаю, потому что у меня есть завершение для отсутствия org.thymeleaf.templateresolver.ServletContextTemplateResolver. Кто-нибудь видит ошибку, которую я делаю? Заранее благодарю за каждый ответ. Я нашел решение, потому что распознаватель нужен аргумент в конструктор, я должен создать ServletContextFactory (как в How to set ServletContext property for a bean in Spring XML metadata configuration) и ввести его в конструктор RESOLVER в:

<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> 

Answer 1

Вам нужно будет подключить в вашем templateEngine к viewResolver. Вот мой работает один:

<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> 

Answer 2

Short
Заменить ThymeleafViewResolver с SpringResourceTemplateResolver:

<bean 
    id="templateResolver" 
    class="org.thymeleaf.spring4.templateresolver.SpringResourceTemplateResolver" 
    p:prefix="/WEB-INF/templates/" 
    p:suffix=".html" 
    p:templateMode="HTML5" 
> 
</bean>

Несколько дней назад у меня была такая же проблема при использовании Tutorial: Thymeleaf + Spring, то немного устарел. Решение было найдено в "Thymeleaf 3 ten-minute migration guide":

Первое различие в конфигурации Thymeleaf 2 является то, что в настоящее время рекомендуемый шаблон распознаватель для Spring приложений SpringResourceTemplateResolver
