SpringBoot进阶之模板引擎（含源码）
在动态HTML实现上Spring Boot依然可以完美胜任，并且提供了多种模板引擎的默认配置支持，所以在推荐的模板引擎下，我们可以很快的上手开发动态网站。
模板引擎种类
Spring Boot提供了默认配置的模板引擎主要有以下几种：
- Thymeleaf
- FreeMarker
- Velocity
- Groovy
- Mustache
当你使用上述模板引擎中的任何一个，它们默认的模板配置路径为：src/main/resources/templates。
Thymeleaf
Thymeleaf是一个XML/XHTML/HTML5模板引擎，可用于Web与非Web环境中的应用开发。Thymeleaf提供了一个用于整合Spring MVC的可选模块，在应用开发中，你可以使用Thymeleaf来完全代替JSP或其他模板引擎，如Velocity、FreeMarker等。
在Spring Boot中使用Thymeleaf，只需要引入下面依赖：
<dependency>
<groupId>org.springframework.bootgroupId>
<artifactId>spring-boot-starter-thymeleafartifactId>
dependency>案例-遍历所有学生信息
效果图：
工程结构
root package结构：com.example.myproject 应用主类Application.java置于rootpackage下，通常我们会在应用主类中做一些框架配置扫描等配置，我们放在root package下可以帮助程序减少手工配置来加载到我们希望被Spring加载的内容
- 实体（Entity）与数据访问层（Repository）置于com.example.myproject.domain包下
- 逻辑层（Service）置于com.example.myproject.service包下
- Web层（web）置于com.example.myproject.web包下
实体类 Student .java
package com.javazhan.domain;
public class Student {
private int id ;
private String name ;
private int age ;
private String address ;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
}web层 StudentController .java
package com.javazhan.controller;
import java.util.ArrayList;
import java.util.List;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import com.javazhan.domain.Student;
@Controller
public class StudentController {
@RequestMapping("/getStudentList")
public String getStudentList(ModelMap map) {
List list = new ArrayList() ;
for(int i=0; i<=5; i++) {
Student st = new Student() ;
st.setId(i+1) ;
st.setName("章三"+(i+1)) ;
st.setAge(20+i) ;
st.setAddress("北京故宫门牌号20"+i) ;
list.add(st) ;
}
map.addAttribute("list", list);
return "index" ;
}
}
启动类 RunApplication.java
package com.javazhan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class RunApplication {
public static void main(String[] args) {
SpringApplication.run(RunApplication.class, args) ;
}
}

若想修改默认参数配置参考如下，如缓存，编码，修改默认的模板路径等。
# Enable template caching.
spring.thymeleaf.cache=true
# Check that the templates location exists.
spring.thymeleaf.check-template-location=true
# Content-Type value.
spring.thymeleaf.content-type=text/html
# Enable MVC Thymeleaf view resolution.
spring.thymeleaf.enabled=true
# Template encoding.
spring.thymeleaf.encoding=UTF-8
# Comma-separated list of view names that should be excluded from resolution.
spring.thymeleaf.excluded-view-names=
# Template mode to be applied to templates. See also StandardTemplateModeHandlers.
spring.thymeleaf.mode=HTML5
# Prefix that gets prepended to view names when building a URL.
spring.thymeleaf.prefix=classpath:/templates/
# Suffix that gets appended to view names when building a URL.
spring.thymeleaf.suffix=.html spring.thymeleaf.template-resolver-order= # Order of the template resolver in the chain. spring.thymeleaf.view-names= # Comma-separated list of view names that can be resolved.源码下载
