+# FISCO BCOS 合约开发项目
+
+## 项目简介
+
+这是一个基于 FISCO BCOS 区块链平台的 Java 开发项目，提供了与 FISCO BCOS 区块链交互的完整示例代码。项目包含账户管理、智能合约部署和调用等核心功能，适合作为 FISCO BCOS 应用开发的学习和实践基础。
+
+## 技术栈
+
+- **编程语言**: Java
+- **构建工具**: Gradle
+- **区块链平台**: FISCO BCOS
+- **核心依赖**:
+  - FISCO BCOS Java SDK 2.9.1
+  - SLF4J 日志框架
+
+## 主要功能
+
+### 1. 账户管理
+- **账户生成**: 支持生成 ECDSA 和国密 SM 两种加密类型的区块链账户
+- **PEM 格式**: 账户以 PEM 格式存储，包含私钥、公钥和地址信息
+- **账户加载**: 支持从 PEM 文件加载已有账户
+- **多账户管理**: 可批量生成和管理多个用户账户
+
+### 2. 智能合约交互
+- HelloWorld 智能合约示例
+- 合约部署和调用演示
+- 支持使用指定账户与合约交互
+
+### 3. 区块链节点连接
+- 配置化的节点连接管理
+- 支持多种加密类型（ECDSA / 国密 SM）
+- 证书和密钥管理
+
+## 项目结构
+
+```

+```
+
+## 快速开始
+
+### 前置要求
+
+- JDK 8 或更高版本
+- Gradle 6.0 或更高版本
+- FISCO BCOS 区块链节点（运行中）
+
+### 安装与构建
+
+1. 克隆项目到本地
+2. 配置区块链节点连接信息（在 `conf` 目录下）
+3. 构建项目：
+   ```bash
+   ./gradlew build
+   ```
+
+### 运行账户生成工具
+
+```bash
+./gradlew run
+```
+
+该命令会运行 `AccountGenerator` 主类，自动生成示例账户并保存到 `account` 目录。
+
+生成的账户包括：
+- user_pem.pem
+- alice.pem
+- bob.pem
+- charlie.pem
+
+## 使用说明
+
+### 生成账户
+
+```java
+import com.org.fisco.AccountGenerator;
+import org.fisco.bcos.sdk.model.CryptoType;
+
+// 生成 ECDSA 类型账户
+AccountGenerator.generatePEMAccount("myAccount", CryptoType.ECDSA_TYPE);
+
+// 生成国密 SM 类型账户
+AccountGenerator.generatePEMAccount("myAccount", CryptoType.SM_TYPE);
+```
+
+### 加载账户
+
+```java
+// 从 PEM 文件加载账户
+CryptoKeyPair keyPair = AccountGenerator.loadPEMAccount("account/alice.pem", CryptoType.SM_TYPE);
+```
+
+## 配置说明
+
+项目配置文件位于 `conf` 目录，主要包括：
+- 节点连接配置
+- 证书文件
+- 群组配置
+- 加密类型配置
+
+## 开发环境
+
+- IDE: IntelliJ IDEA（推荐）
+- 操作系统: macOS / Linux / Windows
+- Java 版本: JDK 8+
+
+## 许可证
+
+本项目采用开源许可证发布。

+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
