springboot2.0配合thymeleaf实现页面国际化
1. 引入thymeleaf
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.2.1.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>cn.jfjb</groupId> <artifactId>crud</artifactId> <version>0.0.1-SNAPSHOT</version> <name>crud</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <exclusions> <exclusion> <groupId>org.junit.vintage</groupId> <artifactId>junit-vintage-engine</artifactId> </exclusion> </exclusions> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
2. 新建一个“i18n”的包，用来存放国际化配置
写入如下内容
3. application.yml中添加配置参数
spring: messages: basename: i18n.login
4. 编写控制器页面
package cn.jfjb.crud.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; /** * @author john * @date 2019/11/22 - 19:38 */ @Controller @RequestMapping({"/"}) public class HelloController { @RequestMapping({"/"}) public String hello12() { return "index"; } }
5. 编写模板页面
<!DOCTYPE html> <html lang="en" xmlns:th="http://www.thymeleaf.org"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <h1 th:text="#{login.name}"></h1> <h1 th:text="#{login.password}"></h1> </body> </html>
使用th标签之前需要在页面加上xmlns,加上这个之后会有提示!
<html lang="en" xmlns:th="http://www.thymeleaf.org">
然后切换浏览器上面的语言然后刷新页面就会变化
测试
配置使其可以当请求参数中携带语言参数时自动切换语言
1. 编写自定义的LocalResolver
package cn.jfjb.crud.component; import org.springframework.util.StringUtils; import org.springframework.web.servlet.LocaleResolver; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.util.Locale; /** * @author john * @date 2019/11/23 - 21:08 */ public class MyLocalResolver implements LocaleResolver { @Override public Locale resolveLocale(HttpServletRequest req) { // 获取l后面的参数 String l = req.getParameter("l"); Locale locale = Locale.getDefault(); //没有l使用默认配置，有l使用自定义配置 if (!StringUtils.isEmpty(l)) { String[] split = l.split("_"); // 第一个是语言代码 第二个是国家代码 locale = new Locale(split[0], split[1]); } return locale; } @Override public void setLocale(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Locale locale) { } }
2. 把配置加入到SpringBoot的容器中
package cn.jfjb.crud.config; import cn.jfjb.crud.component.MyLocalResolver; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.LocaleResolver; import org.springframework.web.servlet.config.annotation.WebMvcConfigurer; /** * @author john * @date 2019/11/23 - 18:01 */ @Configuration public class MyMvcConfig implements WebMvcConfigurer { @Bean public LocaleResolver localeResolver() { return new MyLocalResolver(); } }
