类中的一个重写hashCode方法

public int hashCode() {
int result = true;
return 1;
}

完整类是这样的

public class DatabaseInitializerPO implements Serializable {
private static final long serialVersionUID = 1L;

public DatabaseInitializerPO() {
}

public boolean equals(Object o) {
    if (o == this) {
        return true;
    } else if (!(o instanceof DatabaseInitializerPO)) {
        return false;
    } else {
        DatabaseInitializerPO other = (DatabaseInitializerPO)o;
        return other.canEqual(this);
    }
}

protected boolean canEqual(Object other) {
    return other instanceof DatabaseInitializerPO;
}

public int hashCode() {
    int result = true;
    return 1;
}

public String toString() {
    return "DatabaseInitializerPO()";
}

}
