最近出现了个这上面的异常,报错异常是说–>变量初始化出现问题，通常出现在静态变量尤其是单例模式。这种问题往往是初始化顺序不对造成的!

报错代码如下:

public class InvestPeopleRes {

    private static List<InvestPeople> investPeopleList ;

    //静态代码块 在jvm在加载类的时候,就已经在执行加载了
    static {
        investPeopleList = new ArrayList<>();
        investPeopleList.add(new InvestPeople("2016-04-06 23:15", 2000.00f, "135******41"));
        investPeopleList.add(new InvestPeople("2016-05-06 08:15", 100.00f, "133******85"));
        investPeopleList.add(new InvestPeople("2016-05-05 17:15", 12430.00f, "136******55"));
    }

    //外界方法调用时,返回对象
    public static List<InvestPeople> getInvestPeopleList() {
        return investPeopleList;
    }
}

即当程序在加载的时候,就会出现investPeopleList 对象的内存泄漏! 解决方案只需要解决investPeopleList对象初始化的问题即可!
方案如下:将investPeopleList 对象初始化放在构造器中其就ok

public class InvestPeopleRes {

    private static List<InvestPeople> investPeopleList ;
    //无参数构造器
    public InverstPeopleRes(){
 investPeopleList = new ArrayList<>();
        investPeopleList.add(new InvestPeople("2016-04-06 23:15", 2000.00f, "135******41"));
        investPeopleList.add(new InvestPeople("2016-05-06 08:15", 100.00f, "133******85"));
        investPeopleList.add(new InvestPeople("2016-05-05 17:15", 12430.00f, "136******55"));
}
    //外界方法调用时,返回对象
    public static List<InvestPeople> getInvestPeopleList() {
        return investPeopleList;
    }
}
