MainModule没加@Views

加了

@IocBean
@Views(value={VelocityViewMaker.class})
public class Main {

我可能加错地方了

现在异常变了

Caused by: java.lang.RuntimeException: java.lang.NoClassDefFoundError: org/apache/velocity/exception/ResourceNotFoundException

没加velocity.jar或maven依赖

文档里没有，我以为不用
我添加了引用

<dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity</artifactId>
            <version>1.7</version>
        </dependency>

现在报错：

还需要 velocity-tools

现在可以了，按照官方文档内容完全是做不到的，建议完善
而且官方文档的

@Ok("vm:tmpl.index") // 模板文件的路径为  /WEB-INF/tmpl/index.vm

这种完全不行，只能按照 @Ok("vm:/tmpl/index.vm")

哦，我改改

现在模版可以读取了，但是不知道怎么传变量到模版去进行判断，比如模版：

#if($info.imgs)  
<img src="$info.imgs" border=0>  
#else  
<img src="noPhoto.jpg">  
#end

这个info对象就不知道如何传进去

所以建议把这个velocity的文档完善
1、有哪些依赖包
2、velocity.properties 放在哪里，我反复调试，必须放在WEB-INF下
3、如何传值到模版
有这些才算是一个比较完整的入门使用文档

这个问题要加精吧

来自美丽的 NutzCN

对象使用方法：
后台代码：

@At("/")
    @Ok("vm:/tmpl/main.vm")
    @Filters(@By(type=CheckSession.class, args={"user", "/login"}))
    public model.User main() {
        model.User user = new User();
        user.setId(1);
        user.setUser_name("nutz");
        user.setRole_id(0);
        return user;
    }

前台使用代码

#if($!{obj.role_id} == 0)
    <li>管理员 $!{obj.user_name}</li>
#else
    <li>普通用户 $!{obj.user_name}</li>
#end

哦, 方法返回值总是叫obj

@wendal 大神，真心希望更新下velocity的使用文档

让其他人少走弯路

已经更新了，如果你可以发pull req的话就更好了

@wendal 能给下我fork的地址吗

任选一个

https://github.com/nutzam/nutzmore

https://gitee.com/nutz/nutzmore

@wendal 已经pull req了

把这里的文档也更新下就最好了 http://www.nutzam.com/core/integration/velocity.html

@qq_b1ca03f7 那你顺便也发一个pull req嘛

https://github.com/nutzam/nutz 在doc/manual目录下面

@wendal OK，pull完毕

好的, 已更新
