带Spring靴的jasypt

Question

我正在使用jasypt spring boot starter:1.14和spring-boot-2.0.0。M2

如果application.properties在类路径（src/main/资源）中可用，它工作得非常好

即使应用程序运行正常，Spring boot也能正常工作。属性放在运行spring boot jar的文件夹中（默认情况下，它在当前文件夹中查找application.properties）

如果我将application.properties移出src/main/资源并将其放在根文件夹中，应用程序无法启动，并出现以下错误

nested exception is java.io.FileNotFoundException: class path resource [application.properties] cannot be opened because it does not exist

通过放置应用程序，我可以运行其他spring boot jar。运行spring boot的文件夹中的属性。但在与jasypt集成后，它就不起作用了

您必须手动解析配置路径。下面的示例实现，其中myapp.home是应用程序参数（或VM选项-

@Configuration
public class Config {
    ...

    @Bean
    private static PropertyPlaceholderConfigurer getCustomPropertyPlaceholderConfigurer() {
        String appPropertyFile = "application.properties";
        String myAppHome = System.getProperty("myapp.home") + + File.separatorChar + "conf";;
        PropertyPlaceholderConfigurer ppc = new PropertyPlaceholderConfigurer();
        final Resource extResource = new FileSystemResource( new File( myAppHome, appPropertyFile) );
        ppc.setLocations( new Resource[] { extResource } );
        ppc.setIgnoreUnresolvablePlaceholders( true );
        return ppc;
    }

    ...
}
