我正在创建一个基于 Spring MVC Maven 模块的项目，因此我将每一层划分为一个 Maven 模块。当我尝试运行基本站点时，代码可以正常编译，但出现错误：

SEVERE: Context initialization failed

我正在尝试将我的"长"代码转换为更简单的lambda驱动代码.想法是从枚举中获取价值.如果第一个值更高或更低,则将其返回并将lambda从进一步打破.我不知道从哪里开始.Lambda从枚举中返回代码,它可以很好地计算差异.我的问题是,一旦发现差异,就会获得返回和/或破坏lambda的值.

代码不起作用:

BiFunction<Map<String, Integer>,Map<String, Integer>,Integer> biFunction = (m1, m2) -> {
    enumWords.forEach(word -> {
        Integer returnValue = 0;
        if(m1.get(word) > m2.get(word)){
            returnValue = m1.get(word).compareTo(m2.get(word));
            break;
        }
    });
    return returnValue;     
};

这是有效的代码(pre-lambda):

BiFunction<Map<String, Integer>,Map<String, Integer>,Integer> biFunction = (m1, m2) -> {
            Integer returnValue = 0;
            if(m1.get("Love") > m2.get("Love")){
                returnValue = -1;
            }else if(m1.get("Love") < m2.get("Love")){
                returnValue = 1;
            }else{
                if(m1.get("You") > m2.get("You")){
                    returnValue = -1;
                }else if(m1.get("You") < m2.get("You")){
                    returnValue = 1;
                }else{
                    if(m1.get("Me") > m2.get("Me")){
                        returnValue = -1;
                    }else if(m1.get("Me") …
