amazon-dynamodb - 当我尝试运行以下代码时，我收到此错误“不支持；需要 @DynamoDBTyped 或 @DynamoDBTypeConverted”

问题描述

当我尝试put在这个实体上运行代码时。我收到@DynamoDBTyped 或@DynamoDBTypeConverted 的错误，但我可以使用从数据库中检索数据get并且delete没有任何问题，我认为问题出在我试图传递给amazon dynamodb 的对象上

@AllArgsConstructor
@NoArgsConstructor
    @DynamoDBTable(tableName = "test1")
    class Test1{

    private String prime
    private String lastname

    @DynamoDBHashKey(attributeName = "prime")
    String getPrime() {
        return prime
    }

    void setPrime(String prime) {
        this.prime = prime
    }

    @DynamoDBAttribute(attributeName = "lastname")
    String getLastname() {
        return lastname
    }

    void setLastname(String lastname) {
        this.lastname = lastname
    }

    @Override
    String toString() {
        return "Test1 [prime=" + prime + ", lastname=" + lastname +"]"
    }
}

和控制器类

    Test1 getTest1(@PathVariable("prime") String prime) {
       return Test1Repository.getTest1ByPrime(prime)
    }

和存储库类

class Test1Repository {

    @Autowired
    private DynamoDBMapper dynamoDBMapper


    Test1 save(Test1 test1) {
        dynamoDBMapper.save(test1)
        return test1
    }

错误是

解决方案

我建议迁移到AWS SDK for Java 2.0
