java开发常用工具类和实体类封装
开源地址

## 使用步骤
### 添加依赖
```
com.litongjava
litongjava-utils
1.1.0
```
默认使用的日志是sfl4j+logback,如果日志框架冲突可以使用下面的配置排除logback
```
com.litongjava
litongjava-utils
1.0.9
ch.qos.logback
logback-classic
```
### 使用工具类
工具类都在com.litongjava.utils下,使用比较简单,基本上看一下就会使用
那个工具类不会用可提issue,我会解答
下面列出一些工具类的使用方法
#### ClassPathUtils
```
URL resource = new ClassPathResource(filepath).getResource();
```
#### ClassPathResource
```
URL url = ClassPathUtils.getResource("timg.jpg");
```
#### ExcelUtils
使用ExcelUtils工具类导出Excel表格
完整代码示例如下
```
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import javax.servlet.http.HttpServletResponse;
import com.litongjava.easyexcel.pojo.Student;
import com.litongjava.utils.excel.ExcelUtils;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("excel")
public class ExcelController {
@RequestMapping("export")
public void export(HttpServletResponse response) {
// 模拟用户查询数据
List data = new ArrayList<>();
data.add(new Student(1, "张1", 11.1, new Date()));
data.add(new Student(2, "张2", 11.2, new Date()));
data.add(new Student(3, "张3", 11.3, new Date()));
data.add(new Student(4, "张4", 11.4, new Date()));
data.add(new Student(5, "张5", 11.5, new Date()));
String filename = "用户管理";
String sheetName = "用户管理";
ExcelUtils.export(response, filename, sheetName, data, Student.class);
}
}
```
### PoiExcelUtils
使用示例读取文件为 List>
```
List> listMap = PoiExcelUtils.readExcel(filepath, 0);
```
完整代码示例如下
excel文件
|id |appid |apisecret |apikey |
|12d28291e4314d48bcdd8a7566ba5337 |qwdfrugi |d8117b01d8e64fe5afffffffffffffff |3718fffffffffffffffffffffffffff |
读取代码
```
package top.ppnt.arcsoft.face;
import java.util.List;
import java.util.Map;
import com.litongjava.utils.excel.PoiExcelUtils;
public class AppidAndSdkKey {
public static void main(String[] args) {
String appId = null;
String sdkKey = null;
String docPath = "D:\\document\\secret\\appkey-and-appscret.xls";
List> listMap = PoiExcelUtils.readExcel(docPath, 0);
for (Map map : listMap) {
if ("12d28291e4314d48bcdd8a7566ba5337".equals(map.get("id"))) {
appId = (String) map.get("appid");
sdkKey = (String) map.get("apisecret");
}
}
System.out.println(appId + " " + sdkKey);
}
}
```
HttpUploadUtils
```
import org.junit.Test;
import com.litongjava.utils.httpclient.HttpUploadUtils;
import lombok.extern.slf4j.Slf4j;
@Slf4j
public class HttpUploadUtilsTest {
@Test
public void testUpload() {
//上传地址
String uploadURL = "https://www.yozodcs.com/fcscloud/file/upload";
//上传文件
String localFilePath = "ppnt-yz-office-agent\\data\\upload\\2022\\8\\28\\22\\键鼠合一.doc";
//上传文件
StringBuilder string = HttpUploadUtils.uploadFile(uploadURL, localFilePath, "file");
log.info("{}",string);
}
}
```
