不存在像默认构造那样的创建者）：无法从[来源：（字符串）处的对象值（没有基于委托或属性的创建者）反序列化

Question

我有一个具有以下三个构造函数的实体

public MyObject() {
   // Default constructor to avoid ambiguity
  }


    public MyObject(String arg1, String arg2, String arg3) {

        AnotherType anothertype = new AnotherType(arg1, arg2, arg3);
        this.anotherTpe = anotherTpe;
      }

      public MyObject(AnotherType anotherType) {

        this.anotherType = anotherType;
      }

然后我编写一个测试来检查反序列化的流程

@Test public void serializesToJSON() 抛出异常 {

final MyObject myObject =
    new MyObject(new AnotherType("arg1", "ar2", "arg3"));

ObjectMapper mapper = new ObjectMapper();
assertThat(MAPPER.readValue(fixture("fixtures/myObject.json"), MyObject.class))
    .isEqualTo(myobject);

}

此操作失败并出现错误

cannot construct instance of `AnotherType` (no Creators, like default construct, exist): cannot deserialize from Object value (no delegate- or property-based Creator)
at [Source: (String)

AnotherType如果“ ”对象需要该类中的默认无参数构造函数（如果这是问题），我无法控制该对象。我应该如何解决这个问题？

我尝试过的其他一些事情

尝试按如下方式初始化映射器

ObjectMapper mapper = new ObjectMapper().enable(JsonParser.Feature.ALLOW_UNQUOTED_FIELD_NAMES)
        .registerModule(new ParameterNamesModule(JsonCreator.Mode.PROPERTIES));

并将以下内容添加到 POM 中

<plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-compiler-plugin</artifactId>
                    <configuration>
                        <source>1.8</source>
                        <target>1.8</target>
                        <fork>true</fork>
                        <compilerArgs>
                            <arg>-Xlint</arg>
                            <arg>-parameters</arg>
                        </compilerArgs>

                    </configuration>
                </plugin>
