一、spring使用thymeleaf做解析器其实很简单，这是基于xml配置的方式
<?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:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:mvc="http://www.springframework.org/schema/mvc" 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 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> <context:component-scan base-package="com.test.controller"></context:component-scan> <!-- 开启mvc注解，可使用@DateTimeFormat,@NumberFormat --> <mvc:annotation-driven></mvc:annotation-driven> <!-- 告知静态文件不要拦截，直接访问，这种方式下面那种要好在可以访问web-info下的资源 --> <mvc:resources location="/WEB-INF/css/" mapping="/css/**"></mvc:resources> <mvc:resources location="/WEB-INF/js/" mapping="/js/**"></mvc:resources> <mvc:resources location="/WEB-INF/images/" mapping="/images/**"></mvc:resources> <!-- 配置默认servlet静态资源访问 --> <!-- <mvc:default-servlet-handler/> --> <!-- SpringResourceTemplateResolver automatically integrates with Spring's own --> <!-- resource resolution infrastructure, which is highly recommended. --> <bean id="templateResolver" class="org.thymeleaf.spring4.templateresolver.SpringResourceTemplateResolver"> <property name="prefix" value="/WEB-INF/templates/" /> <property name="suffix" value=".html" /> <!-- HTML is the default value, added here for the sake of clarity. --> <property name="templateMode" value="HTML" /> <!-- Template cache is true by default. Set to false if you want --> <!-- templates to be automatically updated when modified. --> <property name="cacheable" value="false" />
<property name="characterEncoding" value="UTF-8"/>
</bean> <!-- SpringTemplateEngine automatically applies SpringStandardDialect and --> <!-- enables Spring's own MessageSource message resolution mechanisms. --> <bean id="templateEngine" class="org.thymeleaf.spring4.SpringTemplateEngine"> <property name="templateResolver" ref="templateResolver" /> <!-- Enabling the SpringEL compiler with Spring 4.2.4 or newer can speed up --> <!-- execution in most scenarios, but might be incompatible with specific --> <!-- cases when expressions in one template are reused across different data --> <!-- ypes, so this flag is "false" by default for safer backwards --> <!-- compatibility. --> <property name="enableSpringELCompiler" value="true" /> </bean> <bean class="org.thymeleaf.spring4.view.ThymeleafViewResolver"> <property name="templateEngine" ref="templateEngine" /> <!-- NOTE 'order' and 'viewNames' are optional --> <property name="order" value="1" />
<property name="characterEncoding" value="UTF-8"/>
<!-- Controller中返回的视图名后缀包含leaf的，才会进行解析 --> <!-- <property name="viewNames" value="*leaf" /> --> </bean> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <property name="prefix" value="/WEB-INF/jsps/" /> <property name="suffix" value=".jsp" /> <property name="order" value="2" /> <!-- Controller中返回的视图名后缀包含jsp的，才会进行解析 --> <!-- <property name="viewNames" value="*jsp" /> --> </bean> </beans>
和我们传统的配置文件相比，也就多增加了红色的部分，如果你的项目不会使用到jsp，那么就没有必要再配置jsp的解析器了
二、基于注解的配置，首先这个web.xml需要改动成下面这个样子
<?xml version="1.0" encoding="utf-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1" metadata-complete="true"> <!-- Configure ContextLoaderListener to use AnnotationConfigWebApplicationContext instead of the default XmlWebApplicationContext --> <context-param> <param-name>contextClass</param-name> <param-value> org.springframework.web.context.support.AnnotationConfigWebApplicationContext </param-value> </context-param> <!-- Configuration locations must consist of one or more comma- or space-delimited fully-qualified @Configuration classes. Fully-qualified packages may also be specified for component-scanning --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>com.test.dao.configure.ApplicationConfigure</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>springMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- Configure DispatcherServlet to use AnnotationConfigWebApplicationContext instead of the default XmlWebApplicationContext --> <init-param> <param-name>contextClass</param-name> <param-value> org.springframework.web.context.support.AnnotationConfigWebApplicationContext </param-value> </init-param> <!-- Again, config locations must consist of one or more comma-(逗号) or space-delimited（空格） and fully-qualified @Configuration classes --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>com.test.mvc.configure.SpringWebConfig</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <filter> <filter-name>characterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>characterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
标红部分就是与传统web.xml配置的区别。
下面是声明thymeleaf的java配置方式

templateResolver.setCharacterEncoding("utf-8"); return templateResolver; } /** * thymeleaf的模板引擎 * @return */ @Bean public SpringTemplateEngine templateEngine() { // SpringTemplateEngine automatically applies SpringStandardDialect and // enables Spring's own MessageSource message resolution mechanisms. SpringTemplateEngine templateEngine = new SpringTemplateEngine(); templateEngine.setTemplateResolver(templateResolver()); // Enabling the SpringEL compiler with Spring 4.2.4 or newer can // speed up execution in most scenarios, but might be incompatible // with specific cases when expressions in one template are reused // across different data types, so this flag is "false" by default // for safer backwards compatibility. templateEngine.setEnableSpringELCompiler(true); return templateEngine; } /** * thymeleaf的视图解析器 * @return */ @Bean public ThymeleafViewResolver viewResolver() { ThymeleafViewResolver viewResolver = new ThymeleafViewResolver(); viewResolver.setTemplateEngine(templateEngine());
templateResolver.setCharacterEncoding("utf-8");
return viewResolver;
}
