About

不同于java-springboot-paddleocr ，本项目利用JNI加载paddle-ocr的C++编译后的dll库，并利用springboot进行web部署访问，效果等同于java-springboot-paddleocr。

Getting started

paddle-ocr c++编译的dll库以及模型(det_db:文本检测；cls:文本方向；rec_crnn:文本识别)，下载后放入项目的相应位置如下图：

项目启动后访问 http://localhost:8080/swagger-ui/ 测试

其中：

1./ocr：返回json结果（包括识别的文字，坐标以及置信度）

2./ocr/image：返回识别后绘制的图片结果

Result

/ocr，返回json结果
