我在生成的类中有一个 @XmlEnumValue，我想测试一个 JSON 消息（我将在 JSON 消息中传递必须映射到 @XmlEnumValue 的值）并查看我的值是否被映射。但我无法做到这一点。我通过添加以下代码解决了读取@XmlElement 的类似问题。是否还有支持 @XmlEnumValue 的类似方法？？？我正在寻找这样的注释属性名称..

 <bean id="jaxbAnnotationInspector"
    class="org.codehaus.jackson.xc.JaxbAnnotationIntrospector"/>
<bean id="jacksonObjectMapper" class="org.codehaus.jackson.map.ObjectMapper">
    <property name="annotationIntrospector" ref="jaxbAnnotationInspector"/>
</bean>

我有一个平面目录.我有2个阵列.Array1存储目录的内容(所有.PNG文件).Array2有六个文件.这六个文件与Array1中的六个文件相同.如何使用Array2删除目录中的6个文件？两个数组如下:

array1= (`ls ${files}*.PNG`)
array2= $(find . ! -name 'PHOTO*')

尝试使用for循环,但不知道如何继续:

for files in $array2;do
    rm -f files $array1

我的应用程序有问题,通过JPA找到实体.我得到了例外:

Exception in thread "main" java.lang.IllegalArgumentException: Unknown entity: org.hibernate.jpa.internal.EntityManagerImpl
    at org.hibernate.jpa.spi.AbstractEntityManagerImpl.persist(AbstractEntityManagerImpl.java:1184)
    at test.Test.main(Test.java:50)

我的persistence.xml文件:

<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd" version="2.0">
    <persistence-unit name="JPAService" transaction-type="RESOURCE_LOCAL">

        <properties>

            <property name="hibernate.archive.autodetection" value="class"/>
        </properties>
  </persistence-unit>
</persistence>

执行文件:

package test;

import java.util.Date;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import testo.entities.SiecSprzedazyForm;

public class Test {
    public static void main(String[] args) {
        EntityManagerFactory emf = …

private void save_Click(object sender, EventArgs e)
{
    ACCOUNT.oo.Open();
    string QRY = "insert into size(SIZENO,SIZE,COVERAGE,WEIGHT) 
        values('" + size_id.Text + "','" +txt_size.Text + "','" +txt_coverage.Text  
        + "','" +txt_weight.Text + "')";
    OleDbCommand ODB = new OleDbCommand(QRY,ACCOUNT.oo);
    ODB.ExecuteNonQuery();
    MessageBox.Show("Inserted Sucessfully..");
    ACCOUNT.oo.Close();
}
