How to build custom query in Spring boot for mongodb repository with $and and $or clause?-CodePudding

How to build a custom query for mongodb(using mongodb template) for the following query in Spring boot?

db.getCollection('collectionName').find(
   {$or:[
    {$and:[{"name":"xyz"},{"address:"1234"}]},
    {$and:[{"name":"abc"},{"address":"001"}]},
    {..}
    {..so on..}
    ]})

Can we use Criteria Query to query this?

CodePudding user response：

You can build your query in this way:

Criteria criteria = new Criteria();
criteria.orOperator( 
    Criteria.where("name").is("xyz").and("address").is("1234"),
    Criteria.where("name").is("abc").and("address").is("001"),
    Criteria.where(...),
    Criteria.where(...)
);
Query query = new Query(criteria);
mongoTemplate.find(query, YourClass.class, "CollectionName");

If the number of criteria that you have to use is not fixed, you can populate a list of Criteria and pass it to the orOperator function:

List<Criteria> criterias = new ArrayList<>();
for (...) {
    //populate list
    criterias.add(Criteria.where(...).is(...).and(...).is(...);
}
Criteria criteria = new Criteria();
criteria.orOperator(criterias);
