Dubbo invoke 分号失误

1.环境：

dubbo 版本: 2.7.3

2.在项目配置文件找到dubbo配置相关的内容

dubbo.protocols.dubbo.name=dubbo
dubbo.protocols.dubbo.port=27079
dubbo.registry.check=true

3.用telnet的方式连上dubbo,注意此时就是连上的状态，敲击任意命令才会出现“dubbo>”,提示符

sh-4.2# telnet 127.0.0.1 27079
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.

4.执行invoke调用命令（此时需要特别注意，对于习惯了其他提示符，习惯在命令行加分号的同学，invoke的最后不能加分号）

sh-4.2# telnet 127.0.0.1 27079
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.

5.同样的语句加上分号，报错信息会让人怀疑人生

dubbo>invoke rctc.intserv.facade.api.intserv.mgtapi.IRctcOldDataMigreateCommonApiService.migrateOldApplyDataMigrate("1017","10170001","RC_ZWIS_APPLY","2022-11-03 00:00:00","APPLY_STATUS",[{"keyName":"zwStartDate","keyColumn":"START_TM","columnComments":"查询开始日期"},{"keyName":"zwEndDate","keyColumn":"END_TM","columnComments":"查询结束日期"}]);
Invalid parameters, format: service.method(args)
dubbo>

6.接口以及POJO的部分定义。dubbo的invoke可以很方便的将JSONObject,JSONARRAY与对应的参数匹配。

//POJO
@Data
public class RctcIntservApplyExtColumnDTO implements Serializable {

    private static final long serialVersionUID = 7571827010035691125L;

    /**
     * 对应三方特殊参数key 值
     */
    private String keyName;

    /**
     * 三方特殊参数key 值 对应的 apply 表附加字段
     */
    private String keyColumn;

    /**
     * apply 表附加字段注释
     */
    private String columnComments;

}

//interface
public interface IRctcOldDataMigreateCommonApiService {

    /**
     * @param compCd
     * @param interfaceCd
     * @param tableName
     * @param endDate
     */
    void migrateOldApplyDataMigrate(String compCd, String interfaceCd, String tableName, Date endDate, String applyStatusColumnName, List<RctcIntservApplyExtColumnDTO> extFld);

}
