Question

我看到一个非常奇怪的行为，即将表实体保存在Azure存储表中。我的实体定义如下：

#File name is BatchJobRunTableEntity.java
package com.affinnova.batchJobs.db;

import com.microsoft.azure.storage.table.TableServiceEntity;
import groovy.json.JsonOutput;
import org.bson.types.ObjectId;
import java.util.Date;
import java.util.Map;

public class BatchJobRunTableEntity extends TableServiceEntity {

    public BatchJobRunTableEntity(String jobId, String taskId) {
        this.partitionKey = jobId;
        this.rowKey = taskId;
    }

    public BatchJobRunTableEntity() {
    }

    public String accountId;
    public String jobId;
    public String taskId;
    public String referenceKeys;
    public String meta;
    public String task;
    public String batchServiceIdentifier;
    public String clientGroupId;
    public String state;
    public String createdBy;
    public String lastUpdatedBy;
    public Date dateCreated;
    public Date lastUpdated;

    public void setAccountId(String accountId) {
        this.accountId = accountId;
    }

    public String getAccountId() {
        return this.accountId;
    }

    public void setJobId(String jobId) {
        this.jobId = jobId;
    }

    public String getJobId() {
        return this.jobId;
    }

    public void setTaskId(String taskId) {
        this.taskId = taskId;
    }

    public void setTaskId(ObjectId taskId) {
        this.taskId = String.valueOf(taskId);
    }

    public String getTaskId() {
        return this.taskId;
    }

    public void setReferenceKeys(String referenceKeys) {
        this.referenceKeys = referenceKeys;
    }

    public void setReferenceKeys(Map referenceKeys) {
        this.setReferenceKeys(JsonOutput.toJson(referenceKeys));
    }

    public String getReferenceKeys() {
        return this.referenceKeys;
    }

    public void setMeta(String meta) {
        this.meta = meta;
    }

    public void setMeta(Map meta) {
        this.setMeta(JsonOutput.toJson(meta));
    }

    public String getMeta() {
        return this.meta;
    }

    public void setTask(String task) {
        this.task = task;
    }

    public void setTask(Map task) {
        this.setTask(JsonOutput.toJson(task));
    }

    public String getTask() {
        return this.task;
    }

    public void setBatchServiceIdentifier(String batchServiceIdentifier) {
        this.batchServiceIdentifier = batchServiceIdentifier;
    }

    public String getBatchServiceIdentifier() {
        return this.batchServiceIdentifier;
    }

    public void setClientGroupId(String clientGroupId) {
        this.clientGroupId = clientGroupId;
    }

    public String getClientGroupId() {
        return this.clientGroupId;
    }

    public void setState(String state) {
        this.state = state;
    }

    public String getState() {
        return this.state;
    }

    public void setCreatedBy(String createdBy) {
        this.createdBy = createdBy;
    }

    public String getCreatedBy() {
        return this.createdBy;
    }

    public void setLastUpdatedBy(String lastUpdatedBy) {
        this.lastUpdatedBy = lastUpdatedBy;
    }

    public String getLastUpdatedBy() {
        return this.lastUpdatedBy;
    }

    public void setDateCreated(Date dateCreated) {
        this.dateCreated = dateCreated;
    }

    public Date getDateCreated() {
        return this.dateCreated;
    }

    public void setLastUpdated(Date lastUpdated) {
        this.lastUpdated = lastUpdated;
    }

    public Date getLastUpdated() {
        return this.lastUpdated;
    }
}

我的应用程序在groovy中，我发现groovy类不能很好地与实体对象一起使用，因此我创建了一个Java类。现在，除“ referenceKeys”外的所有内容都存储在表中。最初我以为可能是数据，但是即使我将相同的数据设置为“ referenceKeys”，“ meta”，也只存储了meta，而referenceKeys却被拒绝了。我已经设置了调试点，以确保也设置了数据。

这里是一个例子：

    BatchJobRunTableEntity batchJobRunTableEntityTmp = new BatchJobRunTableEntity("jobA", "taskA")
    batchJobRunTableEntityTmp.setTaskId("taskA")
    batchJobRunTableEntityTmp.setReferenceKeys(["keyA": "a", "keyB": "b"])
    batchJobRunTableEntityTmp.setMeta(["keyA": "a", "keyB": "b"])
    TableResult resultt = cloudTable.execute(TableOperation.insert(batchJobRunTableEntityTmp))

几乎就像在实体中甚至没有定义referenceKeys一样。

我在Java 7中并使用以下依赖项：'com.microsoft.azure:azure-storage:7.0.0'

更新发现这是由于方法重载造成的，我有两种设置方法，一种用于字符串，另一种用于映射。如果我删除了map的重载方法，那么仍然有效，但仍然无法解释为什么它适用于“ meta”而不适用于“ referenceKeys”-轻微的颠簸但可行的事情。

    #HAD TO REMOVE THESE METHODS

    public void setMeta(Map meta) {
        this.setMeta(JsonOutput.toJson(meta));
    }

    public void setReferenceKeys(Map referenceKeys) {
        this.setReferenceKeys(JsonOutput.toJson(referenceKeys));
    }

    public void setMeta(Map meta) {

    }

    public void setReferenceKeys(Map referenceKeys) {
        this.setReferenceKeys(JsonOutput.toJson(referenceKeys));
    }

更新：

也必须删除此方法，在生产中对我不利。因此绝对不支持函数重载。

    public void setTaskId(String taskId) {
        this.taskId = taskId;
    }

TableEntity仅部分保存在auzre存储表中
