基于sample中springboot样例构建复杂springboot应用后读取外部配置文件失败

构建镜像为teaclave/teaclave-java-tee-sdk:v0.1.0-ubuntu18.04，enclave和host子模块的pom.xml（构建部分）都没有改动。
Dockerfile中的启动选项为：
`
CMD ["java", "-cp", "-Dspring.config.location=file:./application.yml", "host-1.0-SNAPSHOT-with-dependency.jar:enclave-1.0-SNAPSHOT-with-dependency.jar", "com.XXX.host.MainAppication"]
`

Start with the Dockerfile CMD and its Java launch arguments, then compare them with the sample application's enclave and host pom.xml files and the expected external application.yml location. Reproduce the failure with teaclave/teaclave-java-tee-sdk:v0.1.0-ubuntu18.04 and confirm that the built application reads the external configuration file successfully.
