Spring Boot 启动时修改上下文
为了让项目在启东时，加载到封装的JAR中的国际化文件
在封装JAR是增加以下配置类
可用于更改启动上下文中的信息
依赖
1 | org.springframework.bootspring-boot-autoconfigure2.7.18 |
示例
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 | import org.apache.commons.lang3.StringUtils;import org.springframework.context.ApplicationContextInitializer;import org.springframework.context.ConfigurableApplicationContext;import org.springframework.core.Ordered;import org.springframework.core.env.ConfigurableEnvironment;import org.springframework.core.env.Environment;import org.springframework.core.env.MapPropertySource;import java.util.HashMap;import java.util.LinkedHashSet;import java.util.Set;public class EnviromentAutoConfigration implements ApplicationContextInitializer, Ordered { @Override public int getOrder() { return Integer.MAX_VALUE; } @Override public void initialize(ConfigurableApplicationContext applicationContext) { ConfigurableEnvironment environment = applicationContext.getEnvironment(); HashMap properties = new HashMap(); properties.put("spring.messages.basename", getMessagesBasenameProperty(environment)); MapPropertySource propertySource = new MapPropertySource("", properties); environment.getPropertySources().addFirst(propertySource); }/**读取指定的国际化文件*/ private static String getMessagesBasenameProperty(Environment environment) { LinkedHashSet<object data-origwidth="" data-origheight="" style="width: 1264px;"> basenames = new LinkedHashSet(); String basenameString = environment.getProperty("spring.messages.basename"); if (StringUtils.isNoneBlank(basenameString)) { basenames.addAll(Set.of(basenameString.split(","))); } basenames.add("messages/xxx_messages"); return String.join(",",basenames); }}</object> |
resources目录下META-INF文件夹spring.factories文件配置指定类
1 2 3 4 | #上下文，环境配置，这个会先读取org.springframework.cloud.BootstrapConfiguration=xxx.EnviromentAutoConfigration#读取@Configuration注解的配置文件org.springframework.boot.autoconfigure.EnableAutoConfiguration= |
总结
以上为个人经验，希望能给大家一个参考，也希望大家多多支持IT俱乐部。
