Spring是如何初始化多個數據源（無彈簧引導）

Question

我試圖從我的application.properties創建數據源2

所有的我發現使用Spring引導或舊XML的方式解決，我不婉使用它。

什麼是這個春季啓動代碼的等價物。

@Bean 
    @Primary 
    @ConfigurationProperties(prefix="datasource.primary") 
    public DataSource primaryDataSource() { 
     return DataSourceBuilder.create().build(); 
    } 

    @Bean 
    @ConfigurationProperties(prefix="datasource.secondary") 
    public DataSource secondaryDataSource() { 
     return DataSourceBuilder.create().build(); 
    } 

我application.properties

datasource.primary.url="url" 
    datasource.primary.username="user" 
    datasource.primary.password="password" 
    datasource.primary.driver-class-name=com.sybase.jdbc2.jdbc.SybDriver 


    datasource.secondary.url="url" 
    datasource.secondary.username="user" 
    datasource.secondary.password="password" 
    datasource.secondary.driver-class-name=com.ibm.db2.jcc.DB2Driver 

堆棧：彈簧芯，彈簧網，彈簧webmvc，春天-TX，彈簧ORM，

<springframework.version>4.2.4.RELEASE</springframework.version> 

我想用@Annotation

Answer 1

好吧，我做到了，我不知道它是否是正確的方式...

@Configuration 
@EnableWebMvc 
@ComponentScan(basePackages = "com.yourootpackage") 
@PropertySource(value = { "classpath:application.properties" }) 
public Class AppConfiguration extends WebMvcConfigurerAdapter { 

@Value("${datasource.primary.url}") 
private String urlDbPrimary; 

@Value("${datasource.primary.username}") 
private String userDbPrimary; 

@Value("${datasource.primary.password}") 
private String pwdDbPrimary; 

@Value("${datasource.primary.driver-class-name}") 
private String driverDbPrimary; 

@Value("${datasource.secondary.url}") 
private String urlDbSecondary; 

@Value("${datasource.secondary.username}") 
private String userDbSecondary; 

@Value("${datasource.secondary.password}") 
private String pwdDbSecondary; 

@Value("${datasource.secondary.driver-class-name}") 
private String driverDbSecondary; 

// same for secondary 

@Bean 
@Primary 
public DataSource dataSourcePrimary() { 
    BasicDataSource dataSource = new BasicDataSource(); 
    dataSource.setDriverClassName(driverDbPrimary); 
    dataSource.setUrl(urlDbPrimary); 
    dataSource.setUsername(userDbPrimary); 
    dataSource.setPassword(pwdDbPrimary); 

    return dataSource; 
} 

@Bean 
public DataSource dataSourceSecondary() { 
    BasicDataSource dataSource = new BasicDataSource(); 
    dataSource.setDriverClassName(driverDbSecondary); 
    dataSource.setUrl(urlDbSecondary); 
    dataSource.setUsername(userDbSecondary); 
    dataSource.setPassword(pwdDbSecondary); 

    return dataSource; 
} 
}
