spring 属性注入问题，为什么生成的对象总是为空？
[size=14px][size=12px]在ssh2项目整合过程中遇到一个问题：
java 代码：
public class LoginAction extends ActionSupport {
private ILoginManager iLoginManager;
private Customer customer;
private String username;
private String password;
public void setILoginManager(ILoginManager loginManager) {
iLoginManager = loginManager;
}
public ILoginManager getILoginManager() {
return iLoginManager;
}
//用户登录
public String customerLogin() throws Exception {
System.out.println("username = " + username);
System.out.println("password = " + password);
System.out.println("iLoginManager = " + iLoginManager);Customer customer = new Customer();
customer.setUsername(username);
customer.setPassword(password);
if (iLoginManager.login(customer)) {
return "success";
}
if(username != null && password != null){
return "success";
}
//PropertyConfigurator.configure("log4j.properties");
//logger.debug("111111111111111");
return "loginfail";
}
}
上面标红的地方就是提示 iLoginManager 为空

麻烦大家帮我分析一下到底是怎么回事，谢谢了！
[解决办法]
private ILoginManager iLoginManager;
属性第二个字母不要大写。
