check the position of Column annotation in java class for the field For Example,consider one table with name STUDENT with 3 column(Name,Roll_No,Marks).
Then make sure you have added below annotation of column before Getter Method instead of Setter method. It will solve ur problem @Column(name = "Name", length = 100)
**@Column(name = "NAME", length = 100)
public String getName() {**
return name;
}
public void setName(String name) {
this.name= name;
}
