问在jackson反序列化期间，json中存在多个别名

EN

// Sample POJO
@lombok.Data
public class A {
    @com.fasterxml.jackson.annotation.JsonAlias("y")
    private int x; // Field names "x" with alias "y"
}

// Executed code
var om = new ObjectMapper().disable(MapperFeature.IGNORE_MERGE_FOR_UNMERGEABLE);
System.out.println(om.readValue("{\"x\": 1}", A.class));
System.out.println(om.readValue("{\"y\": 1}", A.class));
System.out.println(om.readValue("{\"x\": 1, \"y\": 1}", A.class));
System.out.println(om.readValue("{\"x\": 1, \"y\": 2}", A.class));
System.out.println(om.readValue("{\"y\": 1, \"x\": 2}", A.class));

// Output
A(x=1)
A(x=1)
A(x=1)
A(x=2)
A(x=2)
