具体情况如下：
在MainLauncher上增加了 @ChainBy(type= LogChainMaker.class, args={})
LogChainMaker.class文件内容如下

public class LogChainMaker implements ActionChainMaker {

    @Override
    public ActionChain eval(NutConfig config, ActionInfo ai) {
        // 提醒: config可以获取ioc等信息, ai可以获取方法上的各种配置及方法本身
        // 正常处理的列表
        List<Processor> list = new ArrayList<>();
        list.add(new LogTimeProcessor()); // 设置日志处理类
        list.add(new UpdateRequestAttributesProcessor()); // 设置base/msg等内置属性
        list.add(new EncodingProcessor()); // 设置编码信息@Encoding
        list.add(new ModuleProcessor()); // 获取入口类的对象,从ioc或直接new
        list.add(new ActionFiltersProcessor()); // 处理@Filters
        list.add(new AdaptorProcessor()); // 处理@Adaptor
        list.add(new MethodInvokeProcessor()); // 执行入口方法
        list.add(new ViewProcessor()); // 对入口方法进行渲染@Ok
        for (Processor p : list) {
            try {
                p.init(config, ai);
            } catch (Throwable throwable) {
                throwable.printStackTrace();
            }
        }
        // 最后是专门负责兜底的异常处理器,这个处理器可以认为是全局异常处理器,对应@Fail
        Processor error = new FailProcessor();
        try {
            error.init(config, ai);
        } catch (Throwable throwable) {
            throwable.printStackTrace();
        }
        return new NutActionChain(list, error, ai);
    }
}

把 @ChainBy(type= LogChainMaker.class, args={}) 注解去掉，问题就没有了

nutzboot吗？

话说，缺了ShiroProcessor呢

嗯，加了NutShiroProcessor()就可以了，那是不是这种形式，只要引用了新的模块，都需要在eval方法内增加对应的Processor

新模块是指什么?? 你加的基本上就是全部默认Processor了, 然后有两个可选的, Shiro和校验的, 应该不存在其他的了吧

哦，校验的是指的哪个？

org.nutz.plugins.validation.ValidationProcessor

@wendal 加入这个了还是不行，登录不了，也不报错
登录部分代码

@At("/manage")
    @Ok("beetl:/tml/main.btl")
    @RequiresUser
    public UserModel index() {
        Subject subject = SecurityUtils.getSubject();
        UserModel userModel = (UserModel)subject.getPrincipal();
        return userModel;
    }

SimpleAuthorizingRealm代码：

@IocBean(name="shiroRealm")
public class SimpleAuthorizingRealm extends AbstractSimpleAuthorizingRealm {

    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        if (principals == null) {
            throw new AuthorizationException("PrincipalCollection method argument cannot be null.");
        }
        UserModel user = (UserModel) principals.getPrimaryPrincipal();
        if (user == null)
            return null;
        SimpleAuthorizationInfo auth = new SimpleAuthorizationInfo();
        auth.addRole(user.getRealName());
        for (String authPermission : user.getAuthPermissions()) {
            Logs.get().debugf("User [%s] addStringPermission - [%s]", user.getUserName(), authPermission);
            auth.addStringPermission(authPermission);
        }
        return auth;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        SimpleShiroToken upToken = (SimpleShiroToken) token;

        UserModel user = (UserModel)upToken.getPrincipal();
        if (user == null)
            return null;
        return new SimpleAccount(user, user.getPassword(), user.getRealName());
    }
}

依然是去掉@ChainBy(type= LogChainMaker.class, args={}) 后，就可以正常登录了

日志里面有打印动作链的配置, 对比一下里面的处理器顺序

不知道咋看
我把NutShiroProcessor放在第一个也不行

public class LogChainMaker implements ActionChainMaker {

    @Override
    public ActionChain eval(NutConfig config, ActionInfo ai) {
        // 提醒: config可以获取ioc等信息, ai可以获取方法上的各种配置及方法本身
        // 正常处理的列表
        List<Processor> list = new ArrayList<>();
        list.add(new NutShiroProcessor()); // 设置shiro处理类
        list.add(new LogTimeProcessor()); // 设置日志处理类
        list.add(new UpdateRequestAttributesProcessor()); // 设置base/msg等内置属性
        list.add(new EncodingProcessor()); // 设置编码信息@Encoding
        list.add(new ModuleProcessor()); // 获取入口类的对象,从ioc或直接new
        list.add(new ActionFiltersProcessor()); // 处理@Filters
        list.add(new AdaptorProcessor()); // 处理@Adaptor
        list.add(new MethodInvokeProcessor()); // 执行入口方法
        list.add(new ViewProcessor()); // 对入口方法进行渲染@Ok
        for (Processor p : list) {
            try {
                p.init(config, ai);
            } catch (Throwable throwable) {
                throwable.printStackTrace();
            }
        }
        // 最后是专门负责兜底的异常处理器,这个处理器可以认为是全局异常处理器,对应@Fail
        Processor error = new FailProcessor();
        try {
            error.init(config, ai);
        } catch (Throwable throwable) {
            throwable.printStackTrace();
        }
        return new NutActionChain(list, error, ai);
    }
}

找找启动日志，nutz mvc启动那段，里面有动作链的完整列表

默认是这个顺序

{
	"default" : {
		"ps" : [
		      "org.nutz.mvc.impl.processor.UpdateRequestAttributesProcessor",
		      "org.nutz.mvc.impl.processor.EncodingProcessor",
		      "org.nutz.mvc.impl.processor.ModuleProcessor",
		      "!org.nutz.integration.shiro.NutShiroProcessor",
		      "org.nutz.mvc.impl.processor.ActionFiltersProcessor",
		      "org.nutz.mvc.impl.processor.AdaptorProcessor",
		      "!org.nutz.plugins.validation.ValidationProcessor",
		      "org.nutz.mvc.impl.processor.MethodInvokeProcessor",
		      "org.nutz.mvc.impl.processor.ViewProcessor"
		      ],
		"error" : 'org.nutz.mvc.impl.processor.FailProcessor'
	}
}

其中的叹号代表可选, 没这个类就忽略的意思

实在不会看，搜索processor也没有，但是我按照你发的，把NutShiroProcessor放到ModuleProcessor的后面就可以了

额, 正常了?

给你贴例子

20:00:17.063 DEBUG (Scans.java:280) scan - Found 1 resource by src( mvc/nutzbook-mvc-chain.js ) , regex( ^(.+[.])(js|json)$ )
20:00:17.069 DEBUG (JsonActionChainMakerConfiguretion.java:37) <init> - ActionChain Config:
{
   "default": {
      "ps": ["net.wendal.nutzbook.common.mvc.LogTimeProcessor", "net.wendal.nutzbook.common.mvc.DailyUniqueUsersProcessor", "org.nutz.mvc.impl.processor.UpdateRequestAttributesProcessor", "org.nutz.mvc.impl.processor.EncodingProcessor", "org.nutz.mvc.impl.processor.ModuleProcessor", "org.nutz.integration.shiro.NutShiroProcessor", "org.nutz.mvc.impl.processor.ActionFiltersProcessor", "org.nutz.mvc.impl.processor.AdaptorProcessor", "org.nutz.mvc.impl.processor.MethodInvokeProcessor", "org.nutz.mvc.impl.processor.ViewProcessor"],
      "error": "org.nutz.mvc.impl.processor.FailProcessor"
   }
}
20:00:17.069 DEBUG (NutLoading.java:267) createChainMaker - @ChainBy(org.nutz.mvc.impl.NutActionChainMaker)

我的nutzboot，真没有这个打印

加了自定义@ChainBy就没有了,那是默认的JsonActionChainMakerConfiguretion打印的
