DataSourceConfigurer

@Configuration
public class OMSDataSourceConfigurer {

    @Value("${mybatis.configLocation}")
    private Resource configLocation;

    @Primary
    @Bean
    @ConfigurationProperties(prefix = "spring.datasource.oms")
    public DataSourceProperties omsDataSourceProperties() {
        return new DataSourceProperties();
    }

    @Bean(initMethod = "init")
    @Primary
    @ConfigurationProperties("spring.datasource.druid")
    public DruidDataSource omsDataSource(@Qualifier("omsDataSourceProperties") DataSourceProperties dataSourceProperties) {
        return (DruidDataSource) dataSourceProperties.initializeDataSourceBuilder()
                .build();
    }

    @Bean
    @Primary
    public SqlSessionFactory omsSqlSessionFactory(@Qualifier("omsDataSource") DataSource dataSource) throws Exception {
        SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
        bean.setDataSource(dataSource);
        Assert.notNull(this.configLocation, "");
        Assert.isTrue(this.configLocation.exists(), "");
        bean.setConfigLocation(configLocation);
        bean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath:mybatis_mapper/oms/*.xml"));
        return bean.getObject();
    }

    @Bean
    @Primary
    public DataSourceTransactionManager omsTransactionManager(@Qualifier("omsDataSource") DataSource dataSource) {
        return new DataSourceTransactionManager(dataSource);
    }

    @Bean
    @Primary
    public SqlSessionTemplate omsSqlSessionTemplate(@Qualifier("omsSqlSessionFactory") SqlSessionFactory sqlSessionFactory) {
        return new SqlSessionTemplate(sqlSessionFactory);
    }


}

WPMSDataSourceConfigurer

与上面配置相同，不要添加 @Primary

MybatisConfigurer

@Configuration
@ComponentScan("com.gridvo.eagle.repository")
@MapperScan(basePackages = "com.xx.mybatis.oms.dao", sqlSessionTemplateRef = "omsSqlSessionTemplate")
@MapperScan(basePackages = "com.xx.mybatis.startalk.dao", sqlSessionTemplateRef = "starTalkSqlSessionTemplate")
@MapperScan(basePackages = "com.xx.mybatis.logging.dao", sqlSessionTemplateRef = "loggingSqlSessionTemplate")
@MapperScan(basePackages = "com.xxmybatis.wpms.dao", sqlSessionTemplateRef = "wpmsSqlSessionTemplate")
@EnableTransactionManagement(proxyTargetClass = true)
public class MybatisConfigurer {

}
