SpringBoot整合thymeleaf、nginx实现网页静态化

controller层：

@Controller
@RequestMapping("pages")
public class GoodsPageController {
    @Autowired
    private GoodsPageService goodsPageService;
    @Autowired
    private FileService fileService;
    @GetMapping("{spuid}.html")
    public String toPage(Model model, @PathVariable(value = "spuid")Long spuid) throws Exception {
        Map map = goodsPageService.getData(spuid);
        model.addAllAttributes(map);
        //页面静态化
        fileService.asyncExecute(spuid);
        return "item";
    }
}

service层：

@Slf4j
@Service
public class FileServiceImpl implements FileService {
    @Autowired
    private GoodsPageService goodsPageService;
    @Autowired
    private TemplateEngine templateEngine;
    @Value("${ddong.thymeleaf.destPath}")
    private String destPath;
    @Override
    public void createHtml(Long spuid) throws Exception{
            // 创建上下文，
            Context context = new Context();
            // 把数据加入上下文
            context.setVariables(this.goodsPageService.getData(spuid));
            if (!new File(destPath).exists()){
                new File(destPath).mkdirs();
            }
            // 创建输出流，关联到一个临时文件
            File temp = new File(destPath+"/"+spuid + ".html");
            try (PrintWriter writer = new PrintWriter(temp, "UTF-8")) {
                // 利用thymeleaf模板引擎生成 静态页面
                templateEngine.process("item", context, writer);
            } catch (IOException e) {
                log.info("页面静态化出错：{}"+e,spuid);
            }
    }

    /**
     * 新建线程处理页面静态化
     * @param spuid
     */
    @Override
    public void asyncExecute(Long spuid) {
        ThreadUtils.execute(() -> {
            try {
                createHtml(spuid);
            } catch (Exception e) {
                e.printStackTrace();
            }
        });
    }
}

工具类：

public class ThreadUtils {

    private static final ExecutorService es = Executors.newFixedThreadPool(10);

    public static void execute(Runnable runnable){
        es.submit(runnable);
    }
}

nginx配置：

server {
        listen       80;
        server_name  ddong.com;
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
		location /pages {
			# 先找本地
			root html;
			if (!-f $request_filename) { #请求的文件不存在，就反向代理
				proxy_pass http://127.0.0.1:8084;
				break;
			}
		}
    }
