js文件:
var ioc = {
dataSource : {
//type : "org.apache.tomcat.jdbc.pool.DataSource",
type:"com.alibaba.druid.pool.DruidDataSource",
events : {
depose : 'close'
},
fields : {
driverClassName : 'xx',
url : 'xx',
initialSize:15,

}
},
dao : {
type : "org.nutz.dao.impl.NutDao",
args : [{refer:'dataSource'}]
},
testService:{
type:"com.xx.service.TestService"
}
};
module java:
@InjectName("testModule")
@IocBean
public class TestModule {
@Inject
private TestService testService;
@At("tm/getCarBrandList")
@Ok("json")
public Result getCarBrandList() {
Result re = new Result();
testService.getEpSaleFollow2(re, 0L);
return re;
}
}
service java:
@IocBean
public class TestService {
private Logger logger=Logger.getLogger(TestService.class);
@Inject
private Dao dao;
public void getEpSaleFollow2(Result re){
List epSaleFollowList = dao.query(EpSaleFollow.class, Cnd.where("clId", "=", 1).desc("followDate").desc("id"));
re.setList1(epSaleFollowList);
}
}
debug的时候看了 dao是null
43行就是List epSaleFollowList = dao.query(EpSaleFollow.class, Cnd.where("clId", "=", 1).desc("followDate").desc("id"));
报错信息:
