你好作者，请问有办法获取lambda表达式里调用的具体方法名吗

[ziping95]

例如 list.forEach( e -> test(e) )可否获取到test这个方法名，而不是lambda$1这种

写了一个测试代码：

public class TestLambda {
    public void testList() {
        List<String> list = new ArrayList<>();
        list.forEach(e -> testString(e));
    }

    private void testString(String data) {
        System.out.println(data);
    }
}

生成的方法调用关系如下：

M:1 test.call_graph.lambda.TestLambda:<init>() (O)java.lang.Object:<init>() 13 1
M:6 test.call_graph.lambda.TestLambda:testList() (O)java.util.ArrayList:<init>() 20 1
M:7 test.call_graph.lambda.TestLambda:testList() (D)java.util.function.Consumer:accept(test.call_graph.lambda.TestLambda) 21 1
M:8 test.call_graph.lambda.TestLambda:testList() (LM)test.call_graph.lambda.TestLambda:lambda$testList$1(java.lang.String) 21 1
M:9 test.call_graph.lambda.TestLambda:testList() (I)java.util.List:forEach(java.util.function.Consumer) 21 1
M:10 test.call_graph.lambda.TestLambda:testString(java.lang.String) (M)java.io.PrintStream:println(java.lang.String) 25 1
M:11 test.call_graph.lambda.TestLambda:lambda$testList$1(java.lang.String) (O)test.call_graph.lambda.TestLambda:testString(java.lang.String) 21 1

需要关注的调用关系如下：

M:8 test.call_graph.lambda.TestLambda:testList() (LM)test.call_graph.lambda.TestLambda:lambda$testList$1(java.lang.String) 21 1
M:11 test.call_graph.lambda.TestLambda:lambda$testList$1(java.lang.String) (O)test.call_graph.lambda.TestLambda:testString(java.lang.String) 21 1
M:10 test.call_graph.lambda.TestLambda:testString(java.lang.String) (M)java.io.PrintStream:println(java.lang.String) 25 1

可以看到，以下调用链是可以关联起来的

TestLambda:testList
TestLambda:lambda$testList$1
TestLambda:testString

testList方法需要通过lambda$testList$1方法再关联到testString，不知道这个能不能满足你的要求

可以满足，感谢
