首先需要引入eclipselink包：

			<artifactId>eclipselink</artifactId>
			<version>2.5.0</version>
		</dependency>

import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlRootElement;

import org.eclipse.persistence.oxm.annotations.XmlCDATA;

@XmlRootElement(name="InterBOSS")
@XmlAccessorType(XmlAccessType.FIELD)
public class UserStateRqeMessage {

	@XmlCDATA
	private String SvcCont;

	public String getSvcCont() {

	public void setSvcCont(String svcCont) {
		SvcCont = svcCont;
	}

	public UserStateDetail getSvcCont() {

	}

	public void setSvcCont(UserStateDetail svcCont) {

}
