在 Spring Boot 应用程序 getConnection() 中使用 @autowired 数据源

Question

我已经扫描了互联网以找到如何使用@Autowired private DataSource dataSource; 的示例。有很多地方说可以使用application.properties 进行配置，但没有完整的使用示例。

@UsmanMutawakil

到目前为止我要去的地方......

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

第一个 Spring-Boot 应用程序：

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);
    }
}

第二个 Servlet 初始化器：

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);
    }

}

端点（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);
    }
}

控制器：

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;
    }
}

组件：

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;
    }
}

配置：

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();
    }
}

这会构建和部署，但是在端点中调用 tissSolicitacaoProcedimentoController.tissSolicitacaoProcedimentoOperation(solicitacaoProcedimento); 时，我得到了 java.lang.NullPointerException：

Answer 1

我遇到了 2 个导致我找到解决方案的答案：

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

我对这个烦人问题的最终解决方案：

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

第一个 Spring-Boot 应用程序（来自 spring-boot Incializr）：

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);
    }

}

第二个 Servlet 初始化器（来自 spring-boot Incializr）：

您没有 DataSource bean。如果您在 Spring 环境中有一个可用的数据源，那么它将自动装配到该实现接口位置。在您的配置类中配置一个 dataSource bean（或者如果您勇敢的话，可以配置 XML），这应该可以工作。您的 application.proprties 文件仅公开可在应用程序其他地方使用的值，例如 $spring.datasource.url，而不是输入实际的 URL。

您可以在数据源 bean 创建逻辑中使用 application.properties 文件的属性，但仅将这些值添加到 applicaton.properties 不会创建所需的数据源 bean。

XML 示例：

<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>

如果您使用 @Configuration 类，您可以在没有 XML 的情况下实现相同的目的。在该类中，您可以使用 Java 而不是 XML 来定义与上面相同的内容，并且在需要显式值的地方，您可以使用 ${blah} 之类的引用值来引用您的 application.properties。

@配置示例

@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;
    }


}
