Question

我在tutorial的帮助下创建了一个springboot mutimodule项目两个模块 - 一个后端（java类），另一个forntend（角度5应用程序）我在后端模块中包含了前端模块的依赖项。我正在使用maven资源插件创建一个jar。我也在我的pom.xml中将静态资源复制到build目录的静态文件夹中。我还有一个@Controller返回＆＃34; index＆＃34;。当我运行jar时，我希望看到index.html（前端模块）在localhost：8080上呈现。但我得到一个内部服务器错误说＆＃34;模板解析器无法找到索引。我知道@Contoller从模板文件夹中呈现HTML，但在我的情况下，我希望它从前端模块呈现。

这是前端模块的pom.xml是 -

我是springboot的新手，不知道我做错了什么。请帮忙

Answer 1

试试这个对我来说很好。

import java.io.ByteArrayOutputStream;
import java.io.IOException;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;
import org.springframework.stereotype.Controller;
import org.springframework.util.FileCopyUtils;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;


@Controller
public class TestController {

    @RequestMapping(method = RequestMethod.GET)
    public void getIndex(HttpServletRequest request, HttpServletResponse response) throws IOException {
        String uri = request.getRequestURI();
        String accessResource = "/static/index.html";
        if(uri.contains(".")) { // if css or jpg or font or others
            accessResource = "/static" + uri;
        }
        Resource resource;
        ByteArrayOutputStream bos;
        resource = new ClassPathResource(accessResource, TestController.class);
        bos = new ByteArrayOutputStream();
        FileCopyUtils.copy(resource.getInputStream(), bos);
        response.getOutputStream().write(bos.toByteArray());
    }
}

Answer 2

进行以下更改并且有效 - 1.从pom中删除了maven资源插件，而不是添加

<resources>
    <resource>
    <directory>target/frontend</directory>
    <targetPath>static</targetPath>
    </resource>
</resources>
