带弹簧靴的 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/resources ) 中可用，它工作得非常好

即使将 application.properties 放在运行 spring boot jar 的文件夹中，Spring boot 也可以工作（默认情况下，它会在当前文件夹中查找 application.properties）

如果我将 application.properties 移出 src/main/resources 并将其放在根文件夹中，应用程序将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

我可以通过将 application.properties 放在运行 Spring Boot 的文件夹中来运行其他 Spring Boot jar。 但是与 jasypt 集成后，它不起作用

如果任何机构遇到此类问题，请回复

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 -> -Dmyapp.home=c:\my_app）

@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;
    }

    ...
}
