        page.setTotalCount(count);
        page.setTotalPage(count % pageSize == 0 ? count / pageSize : count / pageSize + 1);
        page.setCurrentPage(Long.valueOf(pageSize));

當沒有任何條件時，查出所以文件資料

批量

 @Test
    public void testAccount() {
        BulkOperations ops = mongoTemplate.bulkOps(BulkOperations.BulkMode.UNORDERED, Account.class);
        List<Account> list = new ArrayList<>();
        for (int i = 0; i < 50; i++) {
            Account account = new Account();
            account.setUserName("admin" + i);
            account.setPassWord("password");
            list.add(account);
        }
        ops.insert(list);
        ops.execute();

    }

文件巢狀物件

public class Account{
	...
 	private Set<Role> roles = new HashSet<>();
}

@Test
    public void test9() {
        Query query = new Query();
        Criteria criteria = new Criteria();
        criteria.and("_id").is("364FF769E55A419D8A0F3712C84291AF").and("roles.name").is("admin");
        query.addCriteria(criteria);
        log.debug("result:{}", mongoTemplate.find(query, Account.class));

        //Update update =  Update.update("roles.$.name","admin1");//修改匹配的第一個
        Update update = Update.update("roles.$[].name", "admin1");//修改匹配的所有

        UpdateResult result = mongoTemplate.updateMulti(query, update, Account.class);
        log.debug("UpdateResult:{}", result1);
    }
