1.直接设置SpringMessage的编码

import org.springframework.boot.autoconfigure.AutoConfiguration;
import org.springframework.context.MessageSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.support.ReloadableResourceBundleMessageSource;@AutoConfiguration
public class MessageSourceConfig {@Beanpublic MessageSource messageSource() {ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();messageSource.setBasename("classpath:i18n/messages");messageSource.setDefaultEncoding("UTF-8");return messageSource;}
}

2.使用XML格式的配置文件

import com.zyym.common.core.i18n.XmlMessageSource;
import org.springframework.boot.autoconfigure.AutoConfiguration;
import org.springframework.context.MessageSource;
import org.springframework.context.annotation.Bean;@AutoConfiguration
public class MessageSourceConfig {@Beanpublic MessageSource messageSource() {return new XmlMessageSource(new String[]{"messages"});}
}

import org.springframework.context.support.AbstractMessageSource;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;
import org.springframework.util.DefaultPropertiesPersister;import java.io.IOException;
import java.io.InputStream;
import java.text.MessageFormat;
import java.util.Locale;
import java.util.Properties;public class XmlMessageSource extends AbstractMessageSource {private final Properties properties = new Properties();public XmlMessageSource(String[] basenames) {for (String basename : basenames) {loadProperties(basename);}}private void loadProperties(String basename) {try {Resource resource = new ClassPathResource(basename + ".xml");InputStream inputStream = resource.getInputStream();DefaultPropertiesPersister persister = new DefaultPropertiesPersister();persister.loadFromXml(properties, inputStream);} catch (IOException e) {throw new RuntimeException("Failed to load properties from XML file: " + basename, e);}}@Overrideprotected MessageFormat resolveCode(String code, Locale locale) {String msg = properties.getProperty(code);if (msg != null) {return new MessageFormat(msg, locale);}return null;}@Overrideprotected String resolveCodeWithoutArguments(String code, Locale locale) {return properties.getProperty(code);}
}
