这个错误的意思是说创建signService错误,为啥呢,因为找不到他说依赖的类, 注意这一句Could not autowire field: private com.bboss.nav.db.api.IoDb,说明这个没有定义,为啥呢,命名我的xml配置文件里面有;
解决: 一定要去找webapps里面的部署的项目结构对不对,如果对的话,就看classes文件夹下的文件对不对;
因为我是用tomcat启动的, 在eclipse里右键New->Server这种方式,部署的时候,我工程中src/test/resources目录下有一个applicationContext.xml把src/main/resources中的applicationContext.xml给覆盖了,所以部署的时候删掉src/test/resources目录下的文件或者重命名, 因为这个目录下的文件是测试用的
