Description
package com.example.micrometerdemo;
import com.fasterxml.jackson.annotation.JsonProperty;
import java.lang.reflect.Constructor;
import java.util.Arrays;
public class Snippet {
private String name;
public Snippet(@JsonProperty("name") String name) {
this.name = name;
}
public final String getName() {
Constructor<?> constructor =
Arrays.stream(this.getClass().getDeclaredConstructors())
.filter(
input ->
input.getParameterAnnotations().length > 0
&& input.getParameterAnnotations()[0].length > 0
&& input.getParameterAnnotations()[0][0] instanceof JsonProperty)
.findFirst()
.orElseThrow(
() ->
new IllegalStateException(
"Constructor must have a first parameter annotated with JsonProperty(\"<operator name>\")"));
JsonProperty jsonPropertyAnnotation =
(JsonProperty) constructor.getParameterAnnotations()[0][0];
return jsonPropertyAnnotation.value();
}
public static void main(String[] args) {
new Snippet("am").getName();
}
}
Try to debug the
input.getParameterAnnotations().length > 0
&& input.getParameterAnnotations()[0].length > 0
&& input.getParameterAnnotations()[0][0] instanceof JsonProperty)
By adding a breakpoint at the line input.getParameterAnnotations().length > 0
, when debugging is started the breakpoint is rejected. But if we try to step into filter method and then step into Predicate#test method the debugger comes into this code block and everything like evaluations works.
This works as expected by adding the line breakpoint as mentioned above in Eclipse.
