java获取调用当前方法的方法名和行数

String className = Thread.currentThread().getStackTrace()[2].getClassName();//调用的类名

String methodName = Thread.currentThread().getStackTrace()[2].getMethodName();//调用的方法名

int lineNumber = Thread.currentThread().getStackTrace()[2].getLineNumber();//调用的行数

Thread.currentThread().getStackTrace()[1]是你当前方法执行堆栈

Thread.currentThread().getStackTrace()[2]就是上一级的方法堆栈 以此类推

1.System类

//获取服务器使用的系统

String system = System.getProperty("os.name");

Properties properties = System.getProperties();

for (String name : properties.stringPropertyNames()) {

System.out.println(name);

System.out.println(System.getProperty(name));

//单个实例:输出 os.name Windows 10 一共68组

}

2.EnvironmentAware类可以获取数据源，驱动等

@Configuration

public class EAwareInfo implements EnvironmentAware {

@Override

public void setEnvironment(Environment environment) {

String projectName =environment.getProperty("project.name");

System.out.println(projectName); //获取项目名称

}

}

//逻辑层使用

@Service

public class TestServiceImpl implements TestService, EnvironmentAware {

private static String projectName=null;

@Override

public void setEnvironment(Environment environment) {

//获取项目名称

projectName=environment.getProperty("project.name");

//获取到前缀是"spring.datasource." 的属性列表值.

RelaxedPropertyResolver relaxedPropertyResolver = new RelaxedPropertyResolver(environment, "spring.datasource.");

System.out.println("spring.datasource.url="+relaxedPropertyResolver.getProperty("url"));

}

}
