我正在尝试使用Spring实现LDAP事务。我已经根据spring Doc配置了spring xml，但是在运行程序时我得到了下面提到的错误：
java.lang.IllegalStateException: No value for key [org.springframework.ldap.core.support.LdapContextSource@27bd27bd] bound to thread [main]

注意：我正在尝试回滚LDAP和DB。
代码段：
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.apps.ldap.manager.UserManger;
import com.apps.ldap.model.UserBean;
public class SpringFrameworkLDAPClient {
private static ApplicationContext context = null;
public static void main(String[] args) {
try {
context = new ClassPathXmlApplicationContext("conf/springldap.xml");
UserManger userservice = (UserManger)context.getBean("userManger");
UserBean userbean = new UserBean();
userbean.setCommonName("Santhosh5");
userbean.setLastName("Rajendran5");
userbean.setEmail("rsanthoshkumarr@gmail.com");
userbean.setFirstName("Santhosh5");
userbean.setUserID("Santhosh5");
userservice.createuser(userbean);
} catch (Exception e) {
System.out.println("Error occured " + e);
e.printStackTrace();
}
}
}
UserService
@Transactional
public void createuser(UserBean contactDTO) {
Attributes personAttributes = new BasicAttributes();
BasicAttribute personBasicAttribute = new BasicAttribute("objectclass");
personBasicAttribute.add("person");
personAttributes.put(personBasicAttribute);
personAttributes.put("cn", contactDTO.getCommonName());
personAttributes.put("sn", contactDTO.getLastName());
DistinguishedName newContactDN = new DistinguishedName("ou=users");
newContactDN.add("cn", contactDTO.getCommonName());
ldapTemplate.bind(newContactDN, null, personAttributes);
}
