application.properties文件配置:
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/basedb?characterEncoding=utf-8
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.username=root
spring.datasource.password=root
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
spring.thymleaf.cache = false
spring.thymeleaf.mode=HTML
spring.thymeleaf.suffix=.html
cbs.imagesPath=file:/E:/images/
实体类就不说了,主要是上传图片文件部分,上传之前,因为上传的图片不是放在项目下,而是其他路径,这里是E:/images/路径下,为了能在浏览器中能访问到E:/images/下的图片,需要构建一个虚拟地址:
@Configuration
public class MyWebAppConfigurer extends WebMvcConfigurerAdapter {
// 获取配置文件中图片的路径
@Value("${cbs.imagesPath}")
private String mImagesPath;
// 访问图片方法
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
if (mImagesPath.equals("") || mImagesPath.equals("${cbs.imagesPath}")) {
String imagesPath = MyWebAppConfigurer.class.getClassLoader().getResource("").getPath();
if (imagesPath.indexOf(".jar") > 0) {
imagesPath = imagesPath.substring(0, imagesPath.indexOf(".jar"));
} else if (imagesPath.indexOf("classes") > 0) {
imagesPath = "file:" + imagesPath.substring(0, imagesPath.indexOf("classes"));
}
imagesPath = imagesPath.substring(0, imagesPath.lastIndexOf("/")) + "/images/";
mImagesPath = imagesPath;
System.out.println(mImagesPath);
}
LoggerFactory.getLogger(MyWebAppConfigurer.class).info("imagesPath=" + mImagesPath);
registry.addResourceHandler("/images/**").addResourceLocations(mImagesPath);
super.addResourceHandlers(registry);
}
}
接下来就是上传文件的处理:
//处理文件上传
@RequestMapping(value="/uploadimg")
public @ResponseBody Map<String,Object> demo(@RequestParam(value = "editormd-image-file", required = false) MultipartFile file, HttpServletRequest request) {
Map<String,Object> resultMap = new HashMap<String,Object>();
String fileName = file.getOriginalFilename();
//保存
try {
byte[] bytes = file.getBytes();
Path path = Paths.get(UPLOADED_FOLDER + file.getOriginalFilename());
Files.write(path, bytes);
resultMap.put("success", 1);
resultMap.put("message", "上传成功!");
resultMap.put("url","../images/"+fileName);
} catch (Exception e) {
resultMap.put("success", 0);
resultMap.put("message", "上传失败!");
e.printStackTrace();
}
System.out.println(resultMap.get("success"));
return resultMap;
}
后端部分已经写好,现在来处理前端部分
网上有很多Markdown编辑器,可以自行百度,这是用的是editormd这款富文本编辑器,把下载好的editormd文件夹加到static文件夹中:
