springboot國際化配置

1.在yml文件的spring下加入下面代碼

 messages:
	encoding: UTF-8
    basename: i18n/messages
    cache-second: 3600

2.在resource下創(chuàng)建i18n文件夾

（internationalization國際化，共18個字母簡稱i18n），

里面創(chuàng)建messages.properties（默認文件，非中、英文時讀?。?/p>

• messages_en.properties（英文）
• messages_zh.properties（中文）

這是我用到的內容，可以參考下格式

英文：

NotEmpty=The input cannot be null
PhoneNotEmpty=The cell phone number cannot be empty
EmailNotEmpty=The mailbox cannot be empty
CodeNotEmpty=Verification code cannot be empty
ResendCode=Please resend the verification code
PhoneRegistered=The phone number has been registered
EmailRegistered=Email registered
PhoneNotRegistered=The phone number is not registered
EmailNotRegistered=Email not registered
CodeIncorrect=Verification code is incorrect
RegisterError=Registration failed. Please try again
AuthError=Authorization failed. Please try again
OperationError=Operation failed, please try again
BindingError=Binding failed, please try again
PhoneNotExist=The cell phone number does not exist
EmailNotExist=Email does not exist
PasswordError=Password Error
AccountFrozen=The account has been frozen, please contact customer service
AccountNotAudit=The account has not been audited, please contact customer service
SendError=Failed to send. Please try again

MessageError=Message failed, please try again
ReplyError=Reply failed, please try again
RoomEntryError=Room entry failed. Please try again
RoomExitError=Room exit failed. Please try again

我這里直接寫的是中文，csdn有很多版本，有的是ascii碼，看個人喜好。

如果后面出現(xiàn)中文亂碼情況，修改下這里：

3.后臺公共方法

package com.es.api.modules.common.controller;
import java.util.Locale;
import javax.servlet.http.HttpServletRequest;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.MessageSource;
import org.springframework.context.NoSuchMessageException;
import org.springframework.context.support.ReloadableResourceBundleMessageSource;
import org.springframework.stereotype.Controller;
@Controller
public class I18nController {
    private static final Logger LOGGER = LoggerFactory
            .getLogger(I18nController.class);
    private MessageSource messageSource;
    /**
     * 初始化
     *
     * @return
     */
    private MessageSource initMessageSource() {
        ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
        messageSource.setBasename("i18n/messages");
        messageSource.setDefaultEncoding("UTF-8");
        messageSource.setCacheSeconds(3600);
        return messageSource;
    }
    /**
     * 設置當前的返回信息
     *
     * @param request
     * @param code
     * @return
     */
    public String getMessage(HttpServletRequest request, String code) {
        if (messageSource == null) {
            messageSource = initMessageSource();
        }
        String language = request.getHeader("language");
        //默認沒有就是請求地區(qū)的語言
        Locale locale = null;
        if (language == null) {
            locale = request.getLocale();
        } else if ("en".equals(language)) {
            locale = Locale.ENGLISH;
        } else if ("zh".equals(language)) {
            locale = Locale.CHINA;
        }
        //其余的不正確的默認就是本地的語言
        else {
            locale = request.getLocale();
        }
        String result = null;
        try {
            result = messageSource.getMessage(code, null, locale);
        } catch (NoSuchMessageException e) {
            LOGGER.error("Cannot find the error message of internationalization, return the original error message.");
        }
        if (result == null) {
            return code;
        }
        return result;
    }
}

注意：我app傳回的language是zh和en，所以我的properties文件命名直接是zh和en，這里注意下，不然錯誤提示是亂碼

方法中調用：首先注入工具

@Autowired
private I18nController i18n;
@Autowired
private HttpServletRequest request;

然后

String message = i18n.getMessage(request, "NotEmpty");
return ResponseUtils.error(message);

總結

以上為個人經驗，希望能給大家一個參考，也希望大家多多支持腳本之家。
