测试类如下

package cn.wizzer;

import cn.wizzer.app.cms.modules.models.Cms_news;
import cn.wizzer.app.cms.modules.services.CmsNewsService;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.nutz.dao.Dao;
import org.nutz.ioc.Ioc;
import org.nutz.ioc.loader.annotation.Inject;
import org.nutz.ioc.loader.annotation.IocBean;
import org.nutz.lang.random.R;
import org.nutz.log.Log;
import org.nutz.log.Logs;

@RunWith(MyNutTestRunner.class)
@IocBean // 必须有
public class SimpleTest extends Assert {
    Log log = Logs.get();

    //private static final Log log = Logs.get();

    // 跟通常的@Inject完全一样.
    @Inject("refer:$ioc")
    protected Ioc ioc;

    @Inject
    protected Dao dao;

    @Inject
    protected CmsNewsService cmsNewsService;

    @Test
    public void test_user_service_create_user() {
        dao.create(Cms_news.class, false);
        Cms_news news = new Cms_news();
        news.setTitle("我们都很好");
        String id = R.UU16();
        news.setId(id);
        cmsNewsService.insert(news);
        news = dao.fetch(Cms_news.class, id);
        log.info("newsString:"+news.toString());
    }
}

Runner类如下

package cn.wizzer;

import cn.wizzer.app.web.commons.core.Module;
import org.junit.runners.model.InitializationError;
import org.nutz.mock.NutTestRunner;

/**
 * Created by Wayne on 2017/4/5.
 */
public class MyNutTestRunner extends NutTestRunner {
    public MyNutTestRunner(Class<?> klass) throws InitializationError {
        super(klass);
    }

    public Class<?> getMainModule() {
        return Module.class;
    }

    /**
     * 可覆盖createIoc,实现参数覆盖, bean替换,等定制.
     *//*
    protected Ioc createIoc() {
        Ioc ioc = super.createIoc();
        PropertiesProxy conf = ioc.get(PropertiesProxy.class, "conf");
        conf.put("db.url", "jdbc:h2:~/test");
        return ioc;
    }*/
}

dao.js配置如下：

var ioc = {
		conf : {
			type : "org.nutz.ioc.impl.PropertiesProxy",
			fields : {
				paths : ["config/custom/"]
			}

		}
};

public void exec(Connection conn, DaoStatement st) {
        if (!enable || ("true".equals(st.getContext().attr(CacheSkipMark)))) {
            _exec(conn, st);
            return;
        }
        String prepSql = st.toPreparedStatement();
        if (prepSql == null) {
            _exec(conn, st);
            return;
        }
        SQLStatementParser parser = sqlParser(prepSql);
        List<SQLStatement> statementList = null;
        try {
            statementList = parser.parseStatementList();
        }
        catch (Exception e) {
            log.debug("Exception when parser SQL sql, skip cache detect!! SQL=" + prepSql);
            _exec(conn, st);
            return;
        }

我打断点进入CachedNutDaoExecutor看到DaoStatement 的参数st只有RUN这个字符串

仔细看ehcache.js的注释

需要初始化一下ehcache,不然就npe了

解决了

var ioc = {
		cacheManager2 : {
			type : "net.sf.ehcache.CacheManager",
			factory : "net.sf.ehcache.CacheManager#getCacheManager",
			args : ["nutzwk"] // 对应shiro.ini中指定的ehcache.xml中定义的name
		}
		// 如果shiro和Ehcache独立配置使用，使用以下配置参数
		cacheManager : {
			type : "net.sf.ehcache.CacheManager",
			factory : "net.sf.ehcache.CacheManager#create"
		}
};
