Question

我想为返回的所有不同实体编写一个通用方法消息列表。

Bean Validation constraint(s) violated while executing Automatic Bean Validation on callback event:'prePersist'

例如：伪代码

enter code here
private List<String> constraintViolationsDetected (genericentity) {
    Set<ConstraintViolation<?>> constraintViolations = validator.validate(?);
}

我正在使用javax.persistence [eclipselink-2.6.0]＆amp;斯普林斯

这是我的代码，我想在保存到数据库之前验证DeploymentConfiguration Entity。我还有3个不同的实体 - 我还必须为其他实体编写验证。注意：最后，我将调用这些方法并作为Rest Services（Jersy）公开

1）DeploymentConfiguration是模型/实体

package com.Demo.persistence.model;

import java.io.Serializable;
import java.util.List;
import javax.persistence.Basic;
import javax.persistence.Column;
import javax.persistence.ElementCollection;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.NamedQueries;
import javax.persistence.NamedQuery;
import javax.persistence.Table;
import javax.validation.Valid;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Pattern;
import javax.validation.constraints.Size;

      public class DeploymentConfiguration implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @Column(name= DBConstants.DEPLOYMENT_ID,length = 255)
    @NotNull(message="DepoymentId type must be specified.")
    @Size(min=1, max=255)
    //@Valid
    private String depoymentId;

    @Basic
    @Column(name = DBConstants.SERVER_TYPE_VALUE, length = 255) 
    @NotNull(message="Deployment Server must be specified.")
    @Size(min=1, max=255)
    @Pattern(regexp="^(Dev|QA|Production)$",message="Invalid Servertype
private String deploymentServerValue;

     public String getDepoymentId () {
        return depoymentId;
    }

    public void setConnectionId(String depoymentId) {
        this.depoymentId = depoymentId;
    }

    public String getDeploymentServerValue () {
        return deploymentServerValue;
    }

    public void setDeploymentServerValue (String deploymentServerValue) 
{
        this.deploymentServerValue = deploymentServerValue;
}

2）DaoImplementation

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import java.util.Set;
import javax.persistence.EntityManager;
import javax.persistence.TypedQuery;
import javax.validation.ConstraintViolation;
import javax.validation.Validation;
import javax.validation.Validator;
import javax.validation.ValidatorFactory;
public class DeploymentConfigurationDaoImpl 
{
EntityManagerProvider entityManagerProvider;
public void saveConnectionConfigurations(ConnectionConfiguration connConfig) {
        LOG.debug("Saving depoyment Configuration");
        if (null == connConfig) {
            return;
        }
        EntityManager em = null;
        em = getEntityManagerProvider().getEntityManager();
        try {
            em.getTransaction().begin();

                em.persist(connConfig);
                em.getTransaction().commit();
                em.getEntityManagerFactory().getCache().evictAll();
                LOG.debug("Persisting data");

        } 
catch (Exception ex) 
{
LOG.error("Error while persisting the depoyment Configuration", ex);

} finally {
    if (em != null && em.isOpen())
    em.close();

}

}
