## 注意：
**
①controller的作用域必須入參，要不然返回結果為null
②thymeleaf的 視圖解析器會沖突，只配置一個即可
## 1、pom依賴
<!-- （使用Thymeleaf模板引擎）-->
<dependency>
<groupId>org.thymeleaf</groupId>
<artifactId>thymeleaf</artifactId>
<version>3.0.2.RELEASE</version>
</dependency>
<dependency>
<groupId>org.thymeleaf</groupId>
<artifactId>thymeleaf-spring4</artifactId>
<version>3.0.2.RELEASE</version>
</dependency>
## 2、springmvc-servlet.xml配置
<!-- thymeleaf的視圖解析器 會與沖突ContentNegotiatingViewResolver-->
<bean id="viewResolver" class="org.thymeleaf.spring4.view.ThymeleafViewResolver">
<property name="characterEncoding" value="UTF-8"/>
<property name="templateEngine" ref="templateEngine"/>
</bean>
<!-- 模板引擎 -->
<bean id="templateEngine" class="org.thymeleaf.spring4.SpringTemplateEngine">
<property name="templateResolver" ref="templateResolver"/>
</bean>
<!-- 模板解析器 -->
<bean id="templateResolver" class="org.thymeleaf.templateresolver.ServletContextTemplateResolver">
<constructor-arg ref="servletContext"/>
<property name="prefix" value="/WEB-INF/muke/"/>
<property name="suffix" value=".html"/>
<property name="templateMode" value="HTML5"/>
<property name="cacheable" value="false"/>
<property name="characterEncoding" value="UTF-8"/>
</bean>
## 3、controller存放到作用域中
參數必須入參：
@RequestMapping(value = "/adminLogin",method = RequestMethod.POST)
public String adminLogin(HttpServletRequest req,
HttpServletResponse resp,
Map<String, Object> map,
Model model,
存放值
req.getSession().setAttribute("admin", admin);
req.setAttribute("name", admin);
map.put("admin1", admin);
model.addAttribute("model", admin);
## 4、html中去對應的作用域的值
html頭部增加支持
<html xmlns:th="http://www.thymeleaf.org">
取值
<span class="user" th:text="${session.admin.adminName}"></span>
<span class="user" th:text="${name.adminName}"></span>
<span class="user" th:text="${model.adminName}"></span>
<span class="user" th:text="${admin1.adminName}"></span>
