Posted 2023-04-17 溜溜球_小钢

在SSMS中连接到Dynamics 365 online需要进行以下步骤:

1. 打开SQL Server Management Studio(SSMS)。

2. 单击“连接”按钮，在弹出的下拉菜单中选择“数据库引擎”。

3. 在“连接到服务器”对话框中输入以下信息：

   a. 服务器类型：选择“SQL Server” b. 服务器名称：输入dynamicscrm名字.crm.dynamics.com c. 认证：选择“SQL Server身份验证” d. 登录：输入Dynamics 365的用户名 e. 密码：输入Dynamics 365的密码

4. 单击“选项”按钮，打开“连接属性”对话框。

5. 在“连接属性”对话框中选择“连接”选项卡。

6. 在“连接”选项卡中输入以下信息：

   a. 数据库：输入Dynamics 365的组织名称 b. 应用程序名称：可以输入任意名称 c. 应用程序角色：可以输入任意角色

7. 单击“确定”按钮连接到Dynamics 365 online。

注意：在连接到Dynamics 365 online之前，您需要在Dynamics 365管理中心中启用IP访问以允许来自特定IP地址的连接。您还需要确保您的计算机已安装SQL Server Native Client，以便连接到Dynamics 365 online。

在spring boot中连接到多个数据库

【中文标题】在spring boot中连接到多个数据库

【英文标题】：Connecting to multiple database in spring boot

【发布时间】：2019-01-13 15:03:03

【问题描述】：

我需要在我的项目中连接到两个数据库。所以我创建了两个配置文件。

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories( basePackages = "com.virat.webservices.datastore.v1.Repo"  )
@EntityScan("com.virat.webservices.datastore.v1.Model")
public class V1DBConfig 

@Primary
@Bean( name = "dataSource" )
@ConfigurationProperties( prefix = "v1.datasource" )
public DataSource dataSource()

    return DataSourceBuilder.create().build();


@Primary
@Bean( name = "entityManagerFactory" )
public LocalContainerEntityManagerFactoryBean entityManagerFactory( EntityManagerFactoryBuilder builder,
        @Qualifier( "dataSource" ) DataSource dataSource )

    return builder.dataSource(dataSource).packages("com.virat.webservices.datastore.v1.Model")
            .persistenceUnit("db1").build();


@Primary
@Bean( name = "transactionManager" )
public PlatformTransactionManager transactionManager(
        @Qualifier( "entityManagerFactory" ) EntityManagerFactory entityManagerFactory )

    return new JpaTransactionManager(entityManagerFactory);

和

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories( entityManagerFactoryRef = "v2EntityManagerFactory", transactionManagerRef = "v2TransactionManager",    basePackages = 
    "com.virat.datastore.repository"  )
@EntityScan( "com.virat.datastore.model" )
public class V2DBConfig 

@Bean( name = "v2DataSource" )
@ConfigurationProperties( prefix = "spring.datasource" )
public DataSource dataSource()

    return DataSourceBuilder.create().build();


@Bean( name = "v2EntityManagerFactory" )
public LocalContainerEntityManagerFactoryBean barEntityManagerFactory( EntityManagerFactoryBuilder builder,
        @Qualifier( "v2DataSource" ) DataSource dataSource )

    return builder.dataSource(dataSource).packages("com.virat.model")
            .persistenceUnit("db2").build();


@Bean( name = "v2TransactionManager" )
public PlatformTransactionManager barTransactionManager(
        @Qualifier( "v2EntityManagerFactory" ) EntityManagerFactory barEntityManagerFactory )

    return new JpaTransactionManager(barEntityManagerFactory);

我将我的application.properties 文件配置为，

spring.datasource.type=com.zaxxer.hikari.HikariDataSource
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/db2?      useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=fal.   se&serverTimezone=UTC&useSSL=false
spring.datasource.username=root
spring.datasource.password=
#spring.datasource.pool.size=20
v1.datasource.driver-class-name=com.mysql.jdbc.Driver
v1.datasource.url=jdbc:mysql://localhost:3306/db1?     useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=fal.   se&serverTimezone=UTC&useSSL=false
v1.datasource.username=root
v1.datasource.password=
#v1.datasource.pool.size=20
spring.jpa.properties.hibernate.id.new_generator_mappings=false
v1.jpa.properties.hibernate.id.new_generator_mappings=false
#spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true

但是当我运行应用程序时，抛出了以下异常。

***************************

我无法确定是什么错误。我有两个模块。一个数据库的repository 和entity 类在一个模块中，而另一个数据库的类在另一个模块中。这会导致问题吗？

编辑

我的TaskServiceImpl.java

package com.virat.webservices.services.impl;


@Service
public class TaskServiceImpl implements TaskService 

    private static final Logger LOGGER = LoggerFactory.getLogger(TaskServiceImpl.class);

    @Autowired
    @PersistenceContext(unitName = "v2EntityManagerFactory")
    private EntityManager entityManager;

    @Value( "$file.base.path" )
    private String basePath;

    @Value( "$application.domain" )
    private String applicationDomain;

    @Value( "$application.protocol" )
    private String applicationProtocol;

    @Value( "$server.port" )
    private String serverPort;

    @Override
    @SuppressWarnings( "unchecked" )
    @Transactional( rollbackOn = DataException.class )
    public Integer doSomething( SomeObject someObject,
            UserAccessDetails userAccessDetails ) throws DataException
    
        try
        
            // Do input validations
            if( NullEmptyUtils.isNull(userAccessDetails) || NullEmptyUtils.isNull(someObject) )
            

                throw new DataException(GeneralConstants.EXCEPTION, GeneralConstants.NULL_INPUT_ERROR,
                        HttpStatus.BAD_REQUEST);
            

            // Creates a native mysql query based on the contents of lawyerDiscoveryParamsBean
            /* Should be replaced with criteria API */
            String generatedQuery = DynamicQueryGenerator.getDynamicQuery(someObject, owner);
            LOGGER.info("Generated query: ", generatedQuery);
            Query executableQuery = entityManager.createNativeQuery(generatedQuery, UserModel.class);

            List<UserModel> userModels = executableQuery.getResultList();

            if( userModels.isEmpty() )
            

                return 0;
            

            return 1;

        
        catch( DataException e )
        
            LOGGER.error(GeneralConstants.ERROR, e);
            throw e;
        
        catch( Exception e )
        
            LOGGER.error(GeneralConstants.ERROR, e);
            throw new DataException(GeneralConstants.EXCEPTION, GeneralConstants.SOMETHING_WENT_WRONG,
                    HttpStatus.INTERNAL_SERVER_ERROR);
        
    

【问题讨论】：

能否请您加入TaskServiceImpl？

@Dan 添加了课程

你看过这个问题的答案了吗：***.com/questions/45663025/…

这是另一个值得检查的好资源：roufid.com/spring-boot-multiple-databases-configuration

【参考方案1】：

在您的TaskServiceImpl 中确保您正确注释了 persistenceContext。

例如：

@PersistenceContext(unitName = "entityManagerFactory")
private EntityManager em;

【讨论】：

我采用了同样的方法。但是，现在例外说，Bean named 'v2DataSource' is expected to be of type 'javax.persistence.EntityManagerFactory' but was actually of type 'org.apache.tomcat.jdbc.pool.DataSource'

试过了。它给出了问题中发布的原始异常

删除 @Autowired 之前的 @PersistenceContext 注释

谢谢@Dan。我犯了答案中指定的一些错误。我错了，我都没有正确命名。

【参考方案2】：

在V1DBConfig.java中，注解@EnableJpaRepository其实应该是这样的，

@EnableJpaRepositories( entityManagerFactoryRef = "entityManagerFactory", transactionManagerRef = "transactionManager", basePackages = 
        "com.virat.webservices.datastore.v1.Repo"  )

您已经在V2DBConfig.java 类中完成了配置（查看@EnableJpaRepository 注释）。在V1DBConfig.java 中做同样的事情。

然后，在您的TaskServiceImpl.java 中，提供PersistenceContext，由@Dan 回答。我希望这会有所帮助。
