java8 foreach用法list转map、map转list

@Test
    public void test010(){
        Map<String,String> map = Maps.newHashMap();
        List<BackupQueueManage> backups = Lists.newArrayList();
        BackupQueueManage queue = new BackupQueueManage();
        queue.setQueueName("oracle-090909");
        queue.setDbType("DB2");
        queue.setLinkScriptId("1");
        queue.setScheduleType("0");
        backups.add(queue);
        backups.forEach(e ->{
            map.put("queueName",e.getQueueName());
            map.put("DbType",e.getDbType());
            map.put("LinkScriptId",e.getLinkScriptId());
            map.put("ScheduleType",e.getScheduleType());
        });
        System.out.println(map);
    }

运行结果

{ScheduleType=0, LinkScriptId=1, queueName=oracle-090909, DbType=DB2}

@Test
    public void test010(){
        Map<String,String> map = Maps.newHashMap();
        map.put("queueName","oracle-090909");
        map.put("DbType","DB2");
        map.put("LinkScriptId","1");
        map.put("ScheduleType","0");
        List<Map<String,String>> results = Lists.newArrayList();
        map.forEach((k,v) -> {
            Map<String,String> tempMap = Maps.newHashMap();
            tempMap.put(k,v);
            results.add(tempMap);
        });
        System.out.println(results);
    }

运行结果

[{ScheduleType=0}, {LinkScriptId=1}, {queueName=oracle-090909}, {DbType=DB2}]
