use @autowired datasource in spring boot applicati

Question

I've scanned the internet to find an example of how to use @Autowired private DataSource dataSource;. There are lots of places that say you can configure it using application.properties, but no full usage examples.

Update

@UsmanMutawakil

Where I've got to so far...

application.properties:

spring.datasource.url=jdbc:oracle:oci:@(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = IP_HOST)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = service_name)))
spring.datasource.username=myDBUsrName
spring.datasource.password=myDBPass
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver

1st the Spring-Boot Application:

package br.com.empresa.solicitacaoprocedimento30302;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;


@SpringBootApplication
public class Solicitacaoprocedimento30302Application {

    public static void main(String[] args) {
        SpringApplication.run(Solicitacaoprocedimento30302Application.class, args);
    }
}

2nd Servlet Initializer:

package br.com.empresa.solicitacaoprocedimento30302;

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Solicitacaoprocedimento30302Application.class);
    }

}

Endpoint (jaxws):

package br.com.empresa.solicitacaoprocedimento30302;

import javax.jws.WebService;
import org.springframework.beans.factory.annotation.Autowired;
import br.com.empresa.solicitacaoprocedimento30302.controller.TissSolicitacaoProcedimentoController;
import java.sql.SQLException;


@WebService(serviceName = "tissSolicitacaoProcedimento", portName = "tissSolicitacaoProcedimento_Port", endpointInterface = "br.gov.ans.tiss.ws.tipos.tisssolicitacaoprocedimento.v30302.TissSolicitacaoProcedimentoPortType", targetNamespace = "http://www.ans.gov.br/tiss/ws/tipos/tisssolicitacaoprocedimento/v30302", wsdlLocation = "WEB-INF/wsdl/tissSolicitacaoProcedimentoV3_03_02.wsdl")
public class tissSolicitacaoProcedimentoWSEndpoint {

    @Autowired
    private TissSolicitacaoProcedimentoController tissSolicitacaoProcedimentoController;

    public br.gov.ans.padroes.tiss.schemas.AutorizacaoProcedimentoWS tissSolicitacaoProcedimentoOperation(br.gov.ans.padroes.tiss.schemas.SolicitacaoProcedimentoWS solicitacaoProcedimento) 
            throws br.gov.ans.tiss.ws.tipos.tisssolicitacaoprocedimento.v30302.TissFault,
                   SQLException, Exception 
    {
        return tissSolicitacaoProcedimentoController.tissSolicitacaoProcedimentoOperation(solicitacaoProcedimento);
    }
}

Controller:

package br.com.empresa.solicitacaoprocedimento30302.controller;

import org.springframework.beans.factory.annotation.Autowired;
import br.gov.ans.padroes.tiss.schemas.AutorizacaoProcedimentoWS;
import br.gov.ans.padroes.tiss.schemas.SolicitacaoProcedimentoWS;
import br.gov.ans.padroes.tiss.schemas.ObjectFactory;
import br.com.example.solicitacaoprocedimento30302.auxiliar.ConfigVlr;
import java.sql.SQLException;

import org.springframework.stereotype.Controller;

@Controller("tissSolicitacaoProcedimentoController")
public class TissSolicitacaoProcedimentoController {

    @Autowired
    private ConfigVlr configVlr;

    public AutorizacaoProcedimentoWS tissSolicitacaoProcedimentoOperation(SolicitacaoProcedimentoWS solicitacaoProcedimento) throws SQLException, Exception 
    {
        ObjectFactory objFact = new ObjectFactory();

        AutorizacaoProcedimentoWS retAutorizacaoProcedimentoWS = objFact.createAutorizacaoProcedimentoWS();

        retAutorizacaoProcedimentoWS.setCabecalho(objFact.createAutorizacaoProcedimentoWSCabecalho());
        retAutorizacaoProcedimentoWS.setAutorizacaoProcedimento(objFact.createAutorizacaoProcedimentoWSAutorizacaoProcedimento());

        String item = configVlr.getValor("OWNER", "REQUIRE_LOGIN_WEB_SERVICE");

        retAutorizacaoProcedimentoWS.setHash("item=" + item);

        retAutorizacaoProcedimentoWS.setHash("tissSolicitacaoProcedimentoOperation() SQLException = " + sqlEx.getMessage() + "; class = " + sqlEx.getClass() + "; tissSolicitacaoProcedimentoOperation:GotTo = " + gotTo + "/nStack Trace:/n" + sqlEx.getStackTrace());

        return retAutorizacaoProcedimentoWS;
    }
}

Component:

package br.com.empresa.solicitacaoprocedimento30302.auxiliar;

import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.JDBCType;
import java.sql.SQLException;
import javax.sql.DataSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;


@Component("configVlr")
public class ConfigVlr
{
    @Autowired
    private DataSource dataSource;

    public String getValor(String owner, String variavel) throws SQLException, Exception 
    {
        String ret = null;
        Integer nErroProc = 0;
        String sErroProc = null;
        String call = "{ call OWNER.PCG_OWNER.CONFIG(?, ?, ?, ?, ?) }";


        Connection conn = dataSource.getConnection();

        CallableStatement cstmt = conn.prepareCall(call);

        cstmt.setString(1, owner);
        cstmt.setString(2, variavel);

        cstmt.registerOutParameter(3, JDBCType.VARCHAR, ret);
        cstmt.registerOutParameter(4, JDBCType.NUMERIC, nErroProc);
        cstmt.registerOutParameter(5, JDBCType.VARCHAR, sErroProc);

        cstmt.execute();

        if (nErroProc != 0) {
            throw new Exception("Proc error = " + nErroProc.toString() + " - " + sErroProc);
        }

        return ret;
    }
}

Configuration:

package br.com.empresa.solicitacaoprocedimento30302.configuration;

import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Bean;

import br.com.empresa.solicitacaoprocedimento30302.controller.TissSolicitacaoProcedimentoController;
import br.com.empresa.solicitacaoprocedimento30302.auxiliar.ConfigVlr;


@Configuration
public class ApplicationConfiguration {

    @Bean
    public TissSolicitacaoProcedimentoController tissSolicitacaoProcedimentoController() {
        return new TissSolicitacaoProcedimentoController();
    }

    @Bean
    public ConfigVlr configVlr() {
        return new ConfigVlr();
    }
}

This builds and deploys, but on the call to tissSolicitacaoProcedimentoController.tissSolicitacaoProcedimentoOperation(solicitacaoProcedimento); in the Endpoint, I get java.lang.NullPointerException:

Any help is much appreciated.

Answer 1

I have come across 2 answers which led me to a solution:

1. How can I access the ApplicationContext from within a JAX-WS web service?

2. http://www.benchresources.net/metro-jax-ws-soap-based-web-service-using-top-down-approach-integrating-with-spring-framework

My final solution to this annoying problem:

application.properties:

spring.datasource.url=jdbc:oracle:oci:@(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = host_ip)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = service_name)))
spring.datasource.username=usr
spring.datasource.password=pass
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver

#Extra config
spring.datasource.type=org.apache.tomcat.jdbc.pool.DataSource

#jpa config.
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.Oracle10gDialect

1st the Spring-Boot Application (from spring-boot Inicializr):

package br.com.example.solicitacaoprocedimento30302;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Solicitacaoprocedimento30302Application {

    public static void main(String[] args) {
        SpringApplication.run(Solicitacaoprocedimento30302Application.class, args);
    }

}

2nd Servlet Initializer (from spring-boot Inicializr):

package br.com.example.solicitacaoprocedimento30302;

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Solicitacaoprocedimento30302Application.class);
    }

}

You have no DataSource bean. If you had a datasource been available in the Spring environment then it would be autowired into that implementing interface location. Configure a dataSource bean in your configuration class (or XML if your brave) and this should work. Your application.proprties file is only exposing values that can be used elsewhere in your application like $spring.datasource.url instead of typing the actual URL.

You can use the properties of your application.properties file inside your datasource bean creation logic but just adding those values to applicaton.properties does not create the needed datasource bean.

XML Example:

<bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource" destroy-method="close">
   <property name="driverClassName" value="${dataSource.driverClassName}" />
       <property name="url" value="${dataSource.url}" />
       <property name="username" value="${dataSource.username}" />
       <property name="password" value="${dataSource.password}" />
       <property name="initialSize" value="10"/>
   <property name="maxActive" value="400"/>
   <property name="testWhileIdle" value="true"/>
   <property name="validationQuery" value="${dataSource.validationQuery}"/>
   <property name="validationInterval" value="600000"/>
   <property name="timeBetweenEvictionRunsMillis" value="600000"/>
   <property name="minIdle" value="10"/>
   <property name="maxIdle" value="100"/>
   <property name="testOnBorrow" value="true"/>
   <property name="removeAbandoned" value="true"/>
   <property name="connectionProperties" value="encrypt=true;TrustServerCertificate=true"/>
</bean>

You can achieve the same without XML in your @Configuration class if your using one. Inside that class you can define the same as above using Java instead of XML and where you need explicit values you can reference your application.properties using reference values such as ${blah}.

@Configuration Example

@Configuration    
public class ApplicationConfig {

    //Return connection to the DB, or atleast an abstracted connection to the connection pool (C3P0)
    @Bean
    public DataSource dataSource() {
        ComboPooledDataSource dataSource = new ComboPooledDataSource();
        //Configure your dataSource here
        return dataSource;
    }


}
