在配置好SSM框架后,在 pom.xml 中添加如下依赖
<dependency> <groupId>org.thymeleaf</groupId> <artifactId>thymeleaf-spring5</artifactId> <version>3.0.9.RELEASE</version> </dependency> 复制代码
<bean id="templateResolver" class="org.thymeleaf.spring5.templateresolver.SpringResourceTemplateResolver"> <property name="prefix" value="/WEB-INF/templates/"/> <property name="suffix" value=".html"/> <property name="characterEncoding" value="UTF-8"/> <property name="order" value="1"/> <property name="templateMode" value="HTML5"/> <property name="cacheable" value="false"/> </bean> <bean id="templateEngine" class="org.thymeleaf.spring5.SpringTemplateEngine"> <property name="templateResolver" ref="templateResolver"/> </bean> <bean id="viewResolver" class="org.thymeleaf.spring5.view.ThymeleafViewResolver"> <property name="templateEngine" ref="templateEngine"/> <property name="characterEncoding" value="UTF-8"/> </bean> 复制代码
@Configuration @EnableWebMvc @ComponentScan({"com.example.controller", "com.example.api"}) public class WebConfig implements WebMvcConfigurer { /** * 模板解析器 * * @return */ @Bean public SpringResourceTemplateResolver templateResolver() { SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver(); templateResolver.setPrefix(TEMPLATE_PREFIX); templateResolver.setSuffix(TEMPLATE_SUFFIX); templateResolver.setCacheable(TEMPLATE_CACHEABLE); templateResolver.setCharacterEncoding(CHARACTER_ENCODING); templateResolver.setTemplateMode(TEMPLATE_MODE); templateResolver.setOrder(TEMPLATE_ORDER); return templateResolver; } /** * 模板引擎 * * @return */ @Bean public SpringTemplateEngine springTemplateEngine(SpringResourceTemplateResolver templateResolver) { SpringTemplateEngine templateEngine = new SpringTemplateEngine(); templateEngine.setTemplateResolver(templateResolver); return templateEngine; } /** * 视图解析器 * * @return */ @Bean public ThymeleafViewResolver viewResolver(SpringTemplateEngine springTemplateEngine) { ThymeleafViewResolver viewResolver = new ThymeleafViewResolver(); viewResolver.setTemplateEngine(springTemplateEngine); viewResolver.setCharacterEncoding(CHARACTER_ENCODING); return viewResolver; } //.......其他配置请自行配置 } 复制代码
由于我使用了CONSTANTS类里面的static变量,所以附上Constants类相关的参数
public final static String CHARACTER_ENCODING = "UTF-8"; /** * thymeleaf模板引擎参数 */ public final static String TEMPLATE_PREFIX = "/WEB-INF/templates/"; public final static String TEMPLATE_SUFFIX = ".html"; public final static Boolean TEMPLATE_CACHEABLE = false; public final static String TEMPLATE_MODE = "HTML5"; public final static Integer TEMPLATE_ORDER = 1; 复制代码
此配置需要注意以下几点:
controller:
在ModelMap里面随便设置一点值
@RequestMapping("/test") public String test(ModelMap map) { map.put("thText", "设置文本内容"); map.put("thUText", "设置文本内容"); map.put("thValue", "设置当前元素的value值"); map.put("thEach", Arrays.asList("列表", "遍历列表")); map.put("thIf", "msg is not null"); map.put("thObject", new UserEntity("sadfa","asfasfd","asfsaf","asdfasf","saf","asfd","sadf",1)); return "test"; } 复制代码
test.html
<!DOCTYPE html> <html lang="cn" xmlns:th="http://www.thymeleaf.org"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <h1>TEST</h1> <h2>Thymeleaf</h2> <!--th:text 设置当前元素的文本内容,常用,优先级不高--> <p th:text="${thText}" /> <p th:utext="${thUText}" /> <!--th:value 设置当前元素的value值,常用,优先级仅比th:text高--> <input type="text" th:value="${thValue}" /> <!--th:each 遍历列表,常用,优先级很高,仅此于代码块的插入--> <!--th:each 修饰在div上,则div层重复出现,若只想p标签遍历,则修饰在p标签上--> <div th:each="message : ${thEach}"> <!-- 遍历整个div-p,不推荐--> <p th:text="${message}" /> </div> <div> <!--只遍历p,推荐使用--> <p th:text="${message}" th:each="message : ${thEach}" /> </div> <!--th:if 条件判断,类似的有th:switch,th:case,优先级仅次于th:each, 其中#strings是变量表达式的内置方法--> <p th:text="${thIf}" th:if="${not #strings.isEmpty(thIf)}"></p> <!--th:insert 把代码块插入当前div中,优先级最高,类似的有th:replace,th:include,~{} :代码块表达式 --> <div th:insert="~{grammar/common::thCommon}"></div> <!--th:object 声明变量,和*{} 一起使用--> <div th:object="${thObject}"> <p>ID: <span th:text="*{id}" /></p><!--th:text="${thObject.id}"--> <p>TH: <span th:text="*{username}" /></p><!--${thObject.thName}--> <p>DE: <span th:text="*{password}" /></p><!--${thObject.desc}--> </div> </body> </html> 复制代码
几点注意:
在html首标签里面加上xmlns
<html lang="cn" xmlns:th="http://www.thymeleaf.org"> 复制代码
同样把head的meta设置一个charset=“UTF-8”
至此,你就可以去配置tomcat运行项目了。
