Transaction error when trying to flush the database after persist

Question

I am using java rest service with spring and jpa with hibernate. I can retrieve data to the client application through json, but i cannot persist data, then I get some transation error. I have googled the net and stackoverflow, and I have tried many solutions, but none have worked.

I have pasted the files I think is related to the problem.

Error message: javax.persistence.TransactionRequiredException: no transaction is in progress

Try this by changing your model class : 

@Entity  
@Table(name="<table name in your database>")
public class test {

@Id
@GeneratedValue(strategy = IDENTITY)
@Column(name="<column name in your mysql table>", unique=true, nullable=false)
private int id;  

@Column(name="<column name in your mysql table>")
private String name;

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}
}
