## 安装与配置

请确保已经安装了Java环境，并且配置好了Maven。然后通过以下命令进行安装：

```bash
mvn clean install
```

## 使用示例

maven 导入，直接使用

            <dependency>
                <groupId>com.github.liming495</groupId>
                <artifactId>tools</artifactId>
                <version>1.2.4</version>
            </dependency>

### 加密解密工具

```java
import com.githup.liming495.secret.SM2Utils;

public class Main {
    public static void main(String[] args) throws Exception {
        // 生成密钥对
        SM2Utils.generateKeyPair();

        // 加密
        String publicKey = "publicKey";
        String data = "data";
        String encryptedData = SM2Utils.encrypt(publicKey.getBytes(), data.getBytes());

        // 解密
        String privateKey = "privateKey";
        byte[] decryptedData = SM2Utils.decrypt(privateKey.getBytes(), encryptedData.getBytes());
    }
}
```

### 日期工具

```java
import com.githup.liming495.utils.DateUtils;

public class Main {
    public static void main(String[] args) throws Exception {
        // 获取当前日期
        String currentDate = DateUtils.nowToString();

        // 格式化日期
        String formattedDate = DateUtils.formatDate(new Date(), "yyyy-MM-dd HH:mm:ss");
    }
}
```

### HTTP请求工具

```java
import com.githup.liming495.utils.HttpRequestUtil;

public class Main {
    public static void main(String[] args) throws Exception {
        // 发送GET请求
        String url = "http://example.com";
        String response = HttpRequestUtil.doGet(url, null, null);
    }
}
```

### 字符串工具

```java
import com.githup.liming495.utils.StringUtils;

public class Main {
    public static void main(String[] args) throws Exception {
        // 判断字符串是否为空
        boolean isEmpty = StringUtils.isEmpty("string");

        // 字符串拼接
        String result = StringUtils.join("Hello", " ", "World");
    }
}
```
