# Java函数模板
#### Java函数
以下为Java函数的示例代码模板。
其中每个方法对应特定的触发器事件，打印事件信息并返回响应，可创建相应的触发器并修改函数执行入口，用于测试Java函数。
根据[Java SDK下载](https://function-community.obs.cn-north-1.myhuaweicloud.com/sdk/java/fss-java-sdk-2.0.5.zip)提供的SDK地址，下载JavaRuntime SDK到本地开发环境解压。完整的Java函数开发示例请参考[开发Java事件函数](https://support.huaweicloud.com/devg-functiongraph/functiongraph_devg_02_0001.html)和[使用Java开发HTTP函数](https://support.huaweicloud.com/devg-functiongraph/functiongraph_02_0607.html)。
