springboot+vue实现手写签名 生层代码

这是一个比较复杂的功能,需要前后端配合完成。以下是一个简单的示例代码,供参考:
后端(Spring Boot):
1. 首先,需要引入相关依赖:
```
<dependency>
<groupId>com.github.gcacace</groupId>
<artifactId>java-signature-pad</artifactId>
<version>2.2.0</version>
</dependency>
```
2. 然后,编写一个接口,接受前端传来的签名数据,并将其保存成图片:
```
@RestController
public class SignatureController {
@PostMapping("/saveSignature")
public String saveSignature(@RequestBody String signatureData) {
try {
// 解码签名数据
String base64Image = signatureData.split(",")[1];
byte[] decodedBytes = Base64.getDecoder().decode(base64Image);
// 将签名保存成图片
BufferedImage image = ImageIO.read(new ByteArrayInputStream(decodedBytes));
File outputfile = new File("signature.png");
ImageIO.write(image, "png", outputfile);
return "success";
} catch (IOException e) {
e.printStackTrace();
return "error";
}
}
}
```
前端(Vue):
1. 首先,需要引入相关组件:
```
<template>
<div>
<SignaturePad v-model="signatureData" />
<button @click="saveSignature">保存签名</button>
</div>
</template>
<script>
import SignaturePad from 'vue-signature-pad';
export default {
components: {
SignaturePad,
},
data() {
return {
signatureData: '',
};
},
methods: {
saveSignature() {
axios.post('/saveSignature', this.signatureData);
},
},
};
</script>
```
2. 然后,使用 SignaturePad 组件来进行手写签名:
```
<template>
<div>
<SignaturePad v-model="signatureData" />
<button @click="saveSignature">保存签名</button>
</div>
</template>
```
