将VUE项目打包后放入SpringBoot项目的resources目录下,在浏览页面时刷新可能会出现404错误。
解决办法:新增配置类ErrorConfig
import org.springframework.boot.web.server.ErrorPage;
import org.springframework.boot.web.server.ErrorPageRegistrar;
import org.springframework.boot.web.server.ErrorPageRegistry;
import org.springframework.http.HttpStatus;
import org.springframework.stereotype.Component;
@Component
public class ErrorConfig implements ErrorPageRegistrar {
@Override
public void registerErrorPages(ErrorPageRegistry registry) {
ErrorPage error404Page = new ErrorPage(HttpStatus.NOT_FOUND, "/index.html");
registry.addErrorPages(error404Page);
}
}
