标签显示不出来吗?
${basedir}/src/main/resources/${artifactId}
static/${artifactId}
2019-12-05 16:10
问题已经解决了
在开发环境下获取
URL resource = this.getClass().getClassLoader().getResource("bill-biaobei-tts-server/index.html");
在linux环境下获取
打包时打包到static目录下
```
${basedir}/src/main/resources/${artifactId}
static/${artifactId}
```
启动是传入./static
```
/usr/java/jdk1.8.0_211/bin/java -Xverify:none -cp ./config:./lib/*:./static com.uairobot.bill.biaobei.Application
```
在代码中获取和上面相同,然后在获取parent

@杜福忠 感谢你提供的使用handler的思路 @詹波 希望在后续版本中可以配置action的拦截后缀
2019-09-30 11:53
解决上面的问题,作者已经提供了方法
com.jfinal.core.CPI
// controller._init_(action, request, response, urlPara[0]);
CPI._init_(controller, action, request, response, urlPara[0]);
2019-09-30 11:50
有点小麻烦
controller._init_(action, request, response, urlPara[0]);
在编辑器中出现下面的错误信息
The method _init_(Action, HttpServletRequest, HttpServletResponse, String) from the type Controller is not visible
2019-09-30 11:43
我找到了原因,和解决办法
jfinal-4.2.jar 包中类,com.jfinal.core.ActionHandler的handle方法如下
public void handle(String target, HttpServletRequest request, HttpServletResponse response, boolean[] isHandled) {
if (target.indexOf('.') != -1) {
return ;
}
我感觉作者这样在大代码中写死不是很好,应该允许某些配置的后缀传入进来
2019-09-30 11:34
@杜福忠 测试无效,代码如下
ActionSuffixHandler
```
@Slf4j
public class ActionSuffixHandler extends Handler {
@Override
public void handle(String target, HttpServletRequest request, HttpServletResponse response, boolean[] isHandled) {
log.info("target:" + target);
next.handle(target, request, response, isHandled);
return;
}
}
```
注册handler
````
@Override
public void configHandler(Handlers me) {
me.add(new ActionSuffixHandler());
}
````
显示的日志如下
```
11:32:06.477 INFO com.alit.robot.prepose.handler.ActionSuffixHandler 15 handle - target:/ask.action
```
问题
1.理论上Handler,可以接受所有的 http请求,但是Handler如何http请求转发到指定的controller进行处理呢?
2.我设置me.setDevMode(true);但是访问ask.action时并没有看到访问的参数信息
