Please help me out.

@Autowired

        if (temp == 0) {
            System.out.println("=========================");
            TransactionInterceptor.currentTransactionStatus().setRollbackOnly();

  • On Linux, a default /etc/mongod.conf configuration file is included when using a package manager to install MongoDB.

  • On Windows, a default <install directory>/bin/mongod.cfg configuration file is included during the installation

  • On macOS, a default /usr/local/etc/mongod.conf configuration file is included when installing from MongoDB’s official Homebrew tap.

Add the following config

replication:
   oplogSizeMB: 128
   replSetName: "rs0"
   enableMajorityReadConcern: true

sudo service mongod restart;

mongo;

rs.initiate({
      _id: "rs0",
      version: 1,
      members: [
         { _id: 0, host : "localhost:27017" }
      ]
   }
)

check for the config to be enabled

rs.conf()

we can use the connection URL as

mongodb://localhost/default?ssl=false&replicaSet=rs0&readPreference=primary
