项目基本配置参考文章SpringBoot入门一,使用myEclipse新建一个SpringBoot项目,使用myEclipse新建一个SpringBoot项目即可。现在来给项目添加一个log4j2支持,添加方式非常简单,仅需两步即可，具体内容如下：
<!-- 3.开启thymeleaf模板引擎支持 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>#----------------视图层thymeleaf配置---------------
## 是否开启缓存
spring.thymeleaf.cache=false
## 设置不严格的html
spring.thymeleaf.mode=LEGACYHTML5
## 编码格式
spring.thymeleaf.encoding=utf-8
## 前缀，也就是模板存放的路径,默认是templates,可以不用配置
spring.thymeleaf.prefix=/view/
## 后缀
spring.thymeleaf.suffix=.htmlimport java.util.ArrayList;
import java.util.List;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import com.qfx.common.controller.BaseController;
import com.qfx.demo.bean.User;
@Controller
@RequestMapping("thyemleaf")
public class ThymeleafController extends BaseController {
@RequestMapping("view/first")
public String firstView(){
User user = new User();
user.setUserId("001");
user.setUserName("张三");
user.setUserAge(18);
user.setUserSex(true);

user2.setUserSex(true);
User user3 = new User();
user3.setUserId("003");
user3.setUserName("柳林");
user3.setUserAge(16);

List<User> userList = new ArrayList<User>();
userList.add(user);
userList.add(user2);
userList.add(user3);
List<String> list = new ArrayList<String>();
list.add("123");
list.add("abc");
list.add("哈哈哈");
list.add("((&($*");
request.setAttribute("msg", "欢迎来到thyemleaf的世界!");
request.setAttribute("userList", userList);
request.setAttribute("list", list);
return "firstPage";
