Springcore beanMap的使用

default <S extends V> S save1(K key, S entity){
        IgniteCache<K, V> cache = cache();
        V targetObject = cache.get(key);
        BeanMap sourceBeanMap = BeanMap.create(entity);
        Map<String, Object> sourceMap = new HashMap<>();
        sourceBeanMap.forEach((key1, value) -> {
            sourceMap.put(String.valueOf(key1), value);
        });
        BeanMap targetBeanMap = BeanMap.create(targetObject);
        Map<String, Object> targetMap = new HashMap<>();
        targetBeanMap.forEach((key1, value) -> {
            targetMap.put(String.valueOf(key1), value);
        });
        for (String s : sourceMap.keySet()) {
            if(null != sourceMap.get(s)){
                targetMap.put(s,sourceMap.get(s));
            }
        }
        targetBeanMap.putAll(targetMap);
        cache.put(key,targetObject);
        return (S)targetObject;
    }


    default <S extends V> S save2(K key, S entity){
        IgniteCache<K, V> cache = cache();
        V targetObject = cache.get(key);
        /**
         * 第一次解析后，可以把方法缓存，提高性能
         */
        try {
            Method[] methods = targetObject.getClass().getMethods();
            for (Method targetMethod : methods) {
                String name = targetMethod.getName();
                if(name.startsWith("set")) {
                    String temp = name.substring(3);
                    String methodName = "get" +  temp.substring(0,1).toUpperCase() + temp.substring(1);
                    Method sourceGetMethod = entity.getClass().getMethod(methodName);
                    Object sourceValue = sourceGetMethod.invoke(entity);
                    if(null != sourceValue){
                        targetMethod.invoke(targetObject,sourceValue);
                    }
                }
            }
        } catch (NoSuchMethodException e) {
            throw new RuntimeException(e);
        } catch (InvocationTargetException e) {
            throw new RuntimeException(e);
        } catch (IllegalAccessException e) {
            throw new RuntimeException(e);
        }
        cache.put(key,targetObject);
        return (S)targetObject;
    }

 

反射方式对于boolean型可能没有set，get方法
