直接上代码

@PostMapping("/update")
    public Object update(@RequestBody URLDTO urldto) throws Exception{
        urldto.setName("update");
        Query query = new Query();
        query.addCriteria(Criteria.where("uid").is(urldto.getUid()));
        BasicUpdate update = new BasicUpdate(
                JSON.toJSONString(urldto)
        );
        return mongoTemplate.updateFirst(query, update, GlobalCollectionName.Collection_URL);
    }


    @PostMapping("/updateSelect")
    public Object updateSelect(@RequestBody URLDTO urldto) throws Exception{
        urldto.setName("update");
        Query query = new Query();
        query.addCriteria(Criteria.where("uid").is(urldto.getUid()));
        String data=JSON.toJSONString(urldto);
        BasicUpdate update = new BasicUpdate(
                "{"+"'$set':"+data+"}"
        );
        return mongoTemplate.updateFirst(query, update, GlobalCollectionName.Collection_URL);
    }
