如何更改 Camunda 数据库以接受长字符串变量?

How to ALTER Camunda database to accept long string variables?

我在通过 Camunda Engine 传递长字符串变量(长度超过 4000 个字符)时遇到问题。

有没有办法改变 camunda 数据库来避免这个异常,或者禁用默认的长字符串限制?

import org.camunda.bpm.engine.variable.Variables;
import org.camunda.bpm.engine.variable.Variables.SerializationDataFormats;

variableMap.put("Authorization", Variables
                              .objectValue(authorization)
                                  // tells the engine to use java serialization for persisting the value 
                              .serializationDataFormat(SerializationDataFormats.JAVA)  
                              .create());
