pom.xml增加:

<dependency>   <groupId>org.springframework.boot</groupId>   <artifactId>spring-boot-starter-data-jpa</artifactId></dependency>

配置表同JdbcTemplate配置.

主数据源:

@Configuration@EnableTransactionManagement@EnableJpaRepositories(entityManagerFactoryRef = "entityManagerFactoryPrimary",        transactionManagerRef = "transactionManagerPrimary",        basePackages = {"com.example.demo.p"})public class PrimaryConfig {    @Bean(name = "primaryDataSource")    @Primary    @Qualifier("primaryDataSource")    @ConfigurationProperties(prefix="spring.datasource.primary")    public DataSource primaryDataSource() {        return DataSourceBuilder.create().build();    }

    @Autowired    @Qualifier("primaryDataSource")    private DataSource primaryDatasource;

    //@Primary    //@Bean(name = "entityManagerPrimary")    //public EntityManager entityManager(EntityManagerFactoryBuilder builder) {    //    return entityManagerFactoryPrimary(builder).getObject().createEntityManager();    //}

    //@Autowired    //private JpaProperties jpaProperties;

    //private Map<String, Object> getVendorProperties() {    //    return jpaProperties.getHibernateProperties(new HibernateSettings());//与1.5版本不同,注意.    //}

    @Primary    @Bean(name = "entityManagerFactoryPrimary")    public LocalContainerEntityManagerFactoryBean entityManagerFactoryPrimary(EntityManagerFactoryBuilder builder) {        return builder.                dataSource(primaryDatasource)                //.properties(getVendorProperties())                .packages("com.example.demo.p")                .persistenceUnit("primaryPersistenceUnit")                .build();    }

    @Primary    @Bean(name = "transactionManagerPrimary")    public PlatformTransactionManager transactionManagerPrimary(EntityManagerFactoryBuilder builder) {        return new JpaTransactionManager(entityManagerFactoryPrimary(builder).getObject());    }}

主Entity:

@Entity@Table(name = "xx")public class Dtl {    @Id    @Column(name = "id")    private Long id;

    @Column(name = "TICKER_SYMBOL")    private String tickerSymbol;

    public Dtl() {}

    public Dtl(String tickerSymbol) {        this.tickerSymbol = tickerSymbol;    }

    public Long getId() {        return id;    }

    public String getTickerSymbol() {        return tickerSymbol;    }

    public void setTickerSymbol(String tickerSymbol) {        this.tickerSymbol = tickerSymbol;    }}

主Repository:

public interface GetDtlP extends JpaRepository<Dtl, Long> {    List<Dtl> findByTickerSymbol(String tickerSymbol);}

次数据源:

@Configuration@EnableTransactionManagement@EnableJpaRepositories(entityManagerFactoryRef = "entityManagerFactorySecondary",        transactionManagerRef = "transactionManagerSecondary",        basePackages = {"com.example.demo.s"})public class SecondaryConfig {    @Bean(name = "secondaryDataSource")    @Qualifier("secondaryDataSource")    @ConfigurationProperties(prefix="spring.datasource.secondary")    public DataSource secondaryDataSource() {        return DataSourceBuilder.create().build();    }

    @Autowired    @Qualifier("secondaryDataSource")    private DataSource secondaryDataSource;

    @Autowired    private JpaProperties jpaProperties;

    private Map<String, Object> getVendorProperties() {        return jpaProperties.getHibernateProperties(new HibernateSettings());    }

    @Bean(name = "entityManagerFactorySecondary")    public LocalContainerEntityManagerFactoryBean entityManagerFactorySecondary(EntityManagerFactoryBuilder builder) {        return builder.                dataSource(secondaryDataSource)                .properties(getVendorProperties())                .packages("com.example.demo.s")                .persistenceUnit("SecondaryPersistenceUnit")                .build();    }

    @Bean(name = "transactionManagerSecondary")    public PlatformTransactionManager transactionManagerSecondary(EntityManagerFactoryBuilder builder) {        return new JpaTransactionManager(entityManagerFactorySecondary(builder).getObject());    }}

次Entity:

@Entity@Table(name = "xx")public class Dtl {    @Id    @Column(name = "id")    private Long id;

    @Column(name = "TICKER_SYMBOL")    private String tickerSymbol;

    public Dtl() {}

    public Dtl(String tickerSymbol) {        this.tickerSymbol = tickerSymbol;    }

    public Long getId() {        return id;    }

    public String getTickerSymbol() {        return tickerSymbol;    }

    public void setTickerSymbol(String tickerSymbol) {        this.tickerSymbol = tickerSymbol;    }}

次Repository:

public interface GetDtlS extends JpaRepository<Dtl, Long> {    List<Dtl> findByTickerSymbol(String tickerSymbol);}

测试:

@RunWith(SpringRunner.class)@SpringBootTestpublic class JpaTest {

    @Autowired    protected GetDtlP getDtlP;

    @Autowired    protected GetDtlS getDtlS;

    @Test    public void test() throws Exception {        List a = getDtlP.findByTickerSymbol("3");        List b = getDtlS.findByTickerSymbol("3");        Assert.assertEquals(a, b);    }}
