Spring Boot中使用thymeleaf
Spring Boot支持FreeMarker、Groovy、Thymeleaf和Mustache四种模板解析引擎,官方推荐使用Thymeleaf。
spring-boot-starter-thymeleaf
我们只需要在Spring Boot中使用Thymeleaf只需在pom中加入Thymeleaf的starter即可:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
在Spring Boot 2.1.7.RELEASE版本中,默认的Thymeleaf版本为3.0.11 RELEASE版本。可以通过如下方式改变默认的Thymeleaf版本:
<properties>
<thymeleaf.version>3.0.10.RELEASE</thymeleaf.version>
<thymeleaf-layout-dialect.version>2.0.1</thymeleaf-layout-dialect.version>
</properties>
在Spring Boot中,默认的html页面地址为src/main/resources/templates,默认的静态资源地址为src/main/resources/static。
Thymeleaf默认配置
在Spring Boot配置文件中可对Thymeleaf的默认配置进行修改:
server.servlet.context-path=/web
#开启模板缓存(默认值:true)
spring.thymeleaf.cache=true
#Check that the template exists before rendering it.
spring.thymeleaf.check-template=true
#检查模板位置是否正确(默认值:true)
spring.thymeleaf.check-template-location=true
#Content-Type的值(默认值:text/html)
spring.thymeleaf.servlet.content-type=text/html
#开启MVC Thymeleaf视图解析(默认值:true)
spring.thymeleaf.enabled=true
#模板编码
spring.thymeleaf.encoding=UTF-8
#要被排除在解析之外的视图名称列表,用逗号分隔
spring.thymeleaf.excluded-view-names=
#要运用于模板之上的模板模式。另见StandardTemplate-ModeHandlers(默认值:HTML5)
spring.thymeleaf.mode=HTML5
#在构建URL时添加到视图名称前的前缀(默认值:classpath:/templates/)
spring.thymeleaf.prefix=classpath:/templates/
#在构建URL时添加到视图名称后的后缀(默认值:.html)
spring.thymeleaf.suffix=.html
#Thymeleaf模板解析器在解析器链中的顺序。默认情况下,它排第一位。顺序从1开始,只有在定义了额外的TemplateResolver Bean时才需要设置这个属性。
spring.thymeleaf.template-resolver-order=
#可解析的视图名称列表,用逗号分隔
#spring.thymeleaf.view-names=
一般开发中将spring.thymeleaf.cache设置为false,其他保持默认值即可。
简单示例
编写一个Controller:
@Controller
public class IndexController {
@RequestMapping("/account")
public String index(Model m) {
List<Account> list = new ArrayList<Account>();
list.add(new Account("KangKang", "苍井优", "e10adc3949ba59abbe56e", "超级管理员", "17777777777"));
list.add(new Account("Mike", "麦克", "e10adc3949ba59abbe56e", "管理员", "13444444444"));
list.add(new Account("Jane","简","e10adc3949ba59abbe56e","运维人员","18666666666"));
list.add(new Account("Maria", "小泽玛利亚", "e10adc3949ba59abbe56e", "清算人员", "19999999999"));
m.addAttribute("accountList",list);
return "account";
}
}
编写account.html页面:
public class Account {
private String account;
private String name;
private String password;
private String accountType;
private String tel;
public Account(String account, String name, String password, String accountType, String tel) {
super();
this.account = account;
this.name = name;
this.password = password;
this.accountType = accountType;
this.tel = tel;
}
public String getAccount() {
return account;
}
public void setAccount(String account) {
this.account = account;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getAccountType() {
return accountType;
}
public void setAccountType(String accountType) {
this.accountType = accountType;
}
public String getTel() {
return tel;
}
public void setTel(String tel) {
this.tel = tel;
}
}
