    text
    copied!<p>I am developing an application in Spring MVC using Hibernate and MySQL and I have an issue. I am trying to populate my last modified field in my Java entity using the <code>@PrePersist</code> annotation. I have debugged the code and the method is getting called and the value is getting set. However, the database is throwing a null violation, since it is not writing out the values the <code>@PrePersist</code> method added. Does anyone know how to fix this t write out the data to the database? </p> <p>FYI, besides changing dates, I want to use these JPA annotations to do certain business logic or use something similar to the annotations.</p> <p>The code:</p> <pre><code>@Entity @Table(name = "account") public class Account { @Column(name = "modified_on") @Temporal(TemporalType.TIMESTAMP) @DateTimeFormat(style = "MM") @NotNull() private Calendar modifiedOn; ... getters, setter and other stuff @PrePersist public void prePersist() { Calendar now = Calendar.getInstance(); this.createdOn = now; this.modifiedOn = now; } @PreUpdate public void preUpdate() { Calendar now = Calendar.getInstance(); this.modifiedOn = now; } </code></pre> <p>applicationContext-Persistence.xml</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;beans:beans xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:jee="http://www.springframework.org/schema/jee" xmlns="http://www.springframework.org/schema/data/jpa" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.2.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.2.xsd http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa.xsd"&gt;
