invalid property name not JavaBean compliant

场景：spring注入，提示Invalid  property  name 'CodedbDao' -  not  JavaBean  compliant解决思路

spring注入，提示Invalid property name 'CodedbDao' - not JavaBean compliant
applicationContext.xml:

CodeService.java:

package com.zjm.ssh2.login.services;

import com.zjm.ssh2.login.dao.iface.ICodedbDAO;
import com.zjm.ssh2.login.services.iface.ICodeService;

public class CodeService implements ICodeService {
    public ICodedbDAO CodedbDao;

    public ICodedbDAO getCodedbDao() {
        return CodedbDao;
    }

    public void setCodedbDao(ICodedbDAO codedbDao) {
        CodedbDao = codedbDao;
    }
}

CodedbDAO.java

import com.zjm.ssh2.login.dao.iface.ICodedbDAO;
public class CodedbDAO extends HibernateDaoSupport implements ICodedbDAO {
......
}

applicationContext.xml文件里这行报错：Invalid property name 'CodedbDao' - not JavaBean compliant
请问怎么回事
