注意：以下的代码和例子是建立在前面的SpringBoot项目整合Flowable和flowable实战

调用活动（Call Activity）将参数传递给子流程（Sub Process）

调用活动（Call Activity）有一个属性：在子流程中继承变量
在这里插入图片描述

不同的用户任务获取不同的参数

这里的任务节点【测试用户任务】和【测试用户任务Two】都定义了2个监听器。
【测试用户任务】节点：设置执行监听器CommonExecutionListener用于添加参数，设置任务监听器CommonTaskListener用于获取参数。
delegateExecution.setVariable(“date”, “2022-12-28”); //date参数另一个任务节点的任务监听器可以获取到
delegateExecution.setVariableLocal(“subject”, “english”);//subject参数另一个任务节点的任务监听器无法获取
【测试用户任务Two】节点：设置执行监听器CommonExecutionListenerTwo用于添加参数，设置任务监听器CommonTaskListenerTwo用于获取参数。

注意：Controller的调用代码上篇文章有介绍。

http://localhost:8081/flowable/createFlowInstance
{
    "flowDefinitionName":"TestCallActivity",
    "item":{
        "name":"liufeifei",
        "age":1,
        "salary":100000
    }
}

打印输出：

CommonStartExecutionListener start
CommonStartExecutionListener variables is:{item=ParamItem(name=liufeifei, age=1, salary=100000), flowDefinitionName=TestCallActivity}
CallActivityStartExecutionListener start
CallActivityStartExecutionListener variables is:{item=ParamItem(name=liufeifei, age=1, salary=100000), flowDefinitionName=TestCallActivity, commonStartExecutionListener=CommonStartExecutionListener}
SubProcessExecutionListener start
SubProcessExecutionListener parentVariables is:{callActivityStartExecutionListener=CallActivityStartExecutionListener, item=ParamItem(name=liufeifei, age=1, salary=100000), flowDefinitionName=TestCallActivity, commonStartExecutionListener=CommonStartExecutionListener}
SubProcessExecutionListener variables is:{callActivityStartExecutionListener=CallActivityStartExecutionListener, item=ParamItem(name=liufeifei, age=1, salary=100000), flowDefinitionName=TestCallActivity, commonStartExecutionListener=CommonStartExecutionListener}
CommonExecutionListener start
CommonExecutionListener variables is:{callActivityStartExecutionListener=CallActivityStartExecutionListener, item=ParamItem(name=liufeifei, age=1, salary=100000), flowDefinitionName=TestCallActivity, commonStartExecutionListener=CommonStartExecutionListener, subProcessExecutionListener=SubProcessExecutionListener}
CommonTaskListener start
commonTaskListener variables is:{callActivityStartExecutionListener=CallActivityStartExecutionListener, date=2022-12-28, item=ParamItem(name=liufeifei, age=1, salary=100000), subject=english, flowDefinitionName=TestCallActivity, commonExecutionListener=CommonExecutionListener, commonStartExecutionListener=CommonStartExecutionListener, subProcessExecutionListener=SubProcessExecutionListener}
commonTaskListener date=2022-12-28;subject=english;dateTwo=null;subjectTwo=null
CommonExecutionListenerTwo start
CommonExecutionListenerTwo variables is:{callActivityStartExecutionListener=CallActivityStartExecutionListener, date=2022-12-28, item=ParamItem(name=liufeifei, age=1, salary=100000), commonTaskListener=CommonTaskListener, flowDefinitionName=TestCallActivity, commonExecutionListener=CommonExecutionListener, commonStartExecutionListener=CommonStartExecutionListener, subProcessExecutionListener=SubProcessExecutionListener}
CommonTaskListenerTwo start
CommonTaskListenerTwo variables is:{callActivityStartExecutionListener=CallActivityStartExecutionListener, date=2022-12-28, item=ParamItem(name=liufeifei, age=1, salary=100000), commonTaskListener=CommonTaskListener, flowDefinitionName=TestCallActivity, commonExecutionListener=CommonExecutionListener, commonStartExecutionListener=CommonStartExecutionListener, commonExecutionListenerTwo=CommonExecutionListenerTwo, dateTwo=2023-01-01, subProcessExecutionListener=SubProcessExecutionListener, subjectTwo=math}
CommonTaskListenerTwo date=2022-12-28;subject=null;dateTwo=2023-01-01;subjectTwo=math
createFlowInstance instanceId is:1db5b521-86ba-11ed-92d5-c03c5949a6ca

//两个任务节点提交后输出
CommonEndExecutionListener end
CommonEndExecutionListener variables is:{callActivityStartExecutionListener=CallActivityStartExecutionListener, item=ParamItem(name=liufeifei, age=1, salary=100000), flowDefinitionName=TestCallActivity, commonStartExecutionListener=CommonStartExecutionListener}

总结:
a.开始节点的变量参数 = 创建工作流传入的参数{item=ParamItem(name=liufeifei, age=1, salary=100000), flowDefinitionName=TestCallActivity}。

b.调用活动节点的变量参数 = 开始节点的变量参数 + 开始节点监听器添加的变量commonStartExecutionListener=CommonStartExecutionListener。

c.子流程节点的变量参数 = 调用活动节点的变量参数 + 调用活动节点添加的变量callActivityStartExecutionListener=CallActivityStartExecutionListener。

d.【测试用户任务】节点的任务监听器变量参数 = 子流程节点的变量参数 + 子流程节点添加的变量subProcessExecutionListener=SubProcessExecutionListener + 该节点的执行监听器添加的变量参数(date=2022-12-28, subject=english)。

e.【测试用户任务Two】节点的变量参数 = 子流程节点的变量参数 + 子流程节点添加的变量 subProcessExecutionListener=SubProcessExecutionListener + 【测试用户任务】节点执行监听器添加的全局变量参数(date=2022-12-28) + 该节点的执行监听器添加的变量参数(dateTwo=2023-01-01, subjectTwo=math)。

注意：这个节点是没有获取到【测试用户任务】节点监听器添加的局部变量( subject=english)。

【测试用户任务】节点和【测试用户任务Two】节点是并行的，一个节点能拿到另一个节点添加的全局变量，但是拿不到添加的局部变量。

f.结束节点的变量参数 = 创建工作流传入的参数 + 开始节点监听器添加的变量+ 调用活动节点监听器添加的变量。
注意：调用活动流程的节点是获取不到子流程的参数的。

Spring AI 使用 AWS Amazon Nova 模型

本教程介绍了如何将Amazon Nova大语言模型与Spring AI集成，构建一个具有多模态能力的聊天机器人。首先配置AWS凭证和模型ID，添加必要的Spring AI依赖。然后实现一个基础聊天机器人TataGPT，通过系统提示设定其性格特征。接着扩展功能使其支持处理文本、图像等多种输入格式。文章详细说明了项目设置、IAM权限配置、服务层实现及REST API暴露等关键步骤，展示了如何利用Ama
