Spring Jdbc + Wildfly没有@AutoWired服务层

Question

Good evening guys, I facade some really strange problem during some tests with spring Jdbctemplate + wildfly 10, when I call a soap webservice through soapui my service layer is not injected what makes the eclipse show me a sad and blue NullPointerException.

The Exception:

Caused by: java.lang.NullPointerException

Class that is extended by the dao layer:

package com.gtac.util.dao;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Repository;

@Repository
public class JdbcConnection {

    /** serialVersionUID */
    private static final long serialVersionUID = 8879088860192903041L;

    private JdbcTemplate jdbcTemplate;

    public JdbcTemplate getJdbcTemplate() {
        return this.jdbcTemplate;
    }

    @Autowired
    public void setDataSource(DataSource dataSource) {
        this.jdbcTemplate = new JdbcTemplate(dataSource);
        int i = this.jdbcTemplate.queryForObject("select valor from teste", Integer.class);
    }

    public static long getSerialversionuid() {
        return serialVersionUID;
    }
}

Dao Layer implementation:

package com.gtac.usuario.dao;

import org.springframework.stereotype.Repository;

import com.gtac.util.dao.JdbcConnection;

@Repository
public class UsuarioDaoImpl extends JdbcConnection implements UsuarioDao{

    @Override
    public int numero() {
        return getJdbcTemplate().queryForObject("select * from teste", Integer.class);
    }



}

Dao's layer interface:

package com.gtac.usuario.dao;

public interface UsuarioDao {

    public int numero();

}

Service Implemented

package com.gtac.usuario.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

import com.gtac.usuario.dao.UsuarioDao;

@Service
@Transactional(propagation = Propagation.NOT_SUPPORTED)
public class UsuarioServiceImpl implements UsuarioService {

    @Autowired
    private UsuarioDao usuarioDao;

    @Override
    public int numero() {
        return usuarioDao.numero();
    }

}

Service's layer interface

package com.gtac.usuario.service;

public interface UsuarioService {
    public int numero();
}

WebService layer

package com.gtac.usuario.webservice.soap;

import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;
import javax.jws.soap.SOAPBinding.Use;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.gtac.usuario.service.UsuarioService;

@WebService(serviceName = "UsuarioWebService")
@SOAPBinding(style = Style.RPC, use = Use.LITERAL)
@Service
public class UsuarioWebServiceImpl {

    @Autowired
    private UsuarioService usuarioService;

    @WebMethod
    public int numero() {
        return this.usuarioService.numero();
    }

    @WebMethod(exclude=true)
    public UsuarioService getUsuarioService() {
        return usuarioService;
    }

    @WebMethod(exclude=true)
    public void setUsuarioService(UsuarioService usuarioService) {
        this.usuarioService = usuarioService;
    }

}

There is something that I forgot to mention: When I start the wildfly 10 for the first time it receives the datasource and it is set in the JdbcTemplate.

Another thing: As you can see in the JdbcConnection.java, I have a line doing a select just after the dataSource is inserted into the JdbcTemplate. That works fine.

Answer 1

I solved this problem. The solution was in the manual:

http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#remoting-web-services

I simple should to extend SpringBeanAutowiringSupport in my webservice layer.

package com.gtac.usuario.webservice.soap;

import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;
import javax.jws.soap.SOAPBinding.Use;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.gtac.usuario.service.UsuarioService;

@WebService(serviceName = "UsuarioWebService")
@SOAPBinding(style = Style.RPC, use = Use.LITERAL)
@Service
public class UsuarioWebServiceImpl extends SpringBeanAutowiringSupport  {

    @Autowired
    private UsuarioService usuarioService;

    @WebMethod
    public int numero() {
        return this.usuarioService.numero();
    }

    @WebMethod(exclude=true)
    public UsuarioService getUsuarioService() {
        return usuarioService;
    }

    @WebMethod(exclude=true)
    public void setUsuarioService(UsuarioService usuarioService) {
        this.usuarioService = usuarioService;
    }

}
