Springboot 国际化配置

首先需要在src/main/resources下新建国际化资源文件 配置文件： pom.xml文件：

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <?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>2.2.0.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.zcw.zcw_springboot</groupId> <artifactId>zcw_springboot</artifactId> <version>0.0.1-SNAPSHOT</version> <name>zcw_springboot</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-thymeleaf</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-webflux</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </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>

创建il8nConfig

package com.zcw.zcw_springboot.zcw_springboot.controller; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.boot.autoconfigure.web.servlet.WebMvcProperties; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.LocaleResolver; import org.springframework.web.servlet.config.annotation.InterceptorRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; import org.springframework.web.servlet.i18n.LocaleChangeInterceptor; import org.springframework.web.servlet.i18n.SessionLocaleResolver; import java.util.Locale; /** * @author zhaocunwei * @ClassName: il8nConfig * @Description: TODO * @date 2019/11/1 13:54 */ @Configuration @EnableAutoConfiguration @ComponentScan public class il8nConfig extends WebMvcConfigurerAdapter { @Bean public LocaleResolver localeResolver(){ SessionLocaleResolver slr = new SessionLocaleResolver(); //默认使用的语言 slr.setDefaultLocale(Locale.US); return slr; } @Bean public LocaleChangeInterceptor localeChangeInterceptor(){ LocaleChangeInterceptor lci = new LocaleChangeInterceptor(); //参数名，用于区别使用的语言类型 lci.setParamName("lang"); return lci; } @Override public void addInterceptors(InterceptorRegistry registry){ registry.addInterceptor(localeChangeInterceptor()); } }

Controller类：

package com.zcw.zcw_springboot.zcw_springboot.controller; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.MessageSource; import org.springframework.context.i18n.LocaleContextHolder; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import org.springframework.web.servlet.LocaleResolver; import org.springframework.web.servlet.support.RequestContextUtils; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletRequestWrapper; import javax.servlet.http.HttpServletResponse; import java.util.Locale; /** * @author zhaocunwei * @ClassName: LanguageController * @Description: TODO * @date 2019/11/1 14:19 */ @Controller public class LanguageController { @Autowired MessageSource messageSource; @RequestMapping("/") public String hello(Model model){ Locale locale = LocaleContextHolder.getLocale(); model.addAttribute("message",messageSource.getMessage("message",null,locale)); return "hello"; } }

前端页面：

<!DOCTYPE html> <html lang="en" xmlns:th="http://www.w3.org/1999/xhtml"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <a href="/?lang=en_US">English(US)</a> <a href="/?lang=zh_CN">简体中文</a></br> <p><label th:text="#{message}"></label></p> </body> </html>
