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
<dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-autoconfigure</artifactid> <version>2.7.18</version> </dependency>
示例
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<configurableapplicationcontext>, ordered { @override public int getorder() { return integer.max_value; } @override public void initialize(configurableapplicationcontext applicationcontext) { configurableenvironment environment = applicationcontext.getenvironment(); hashmap<string, object> 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> 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); } }
resources
目录下meta-inf
文件夹spring.factories
文件配置指定类
#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代码网。
