springboot+mybatis+mapper 多數據源映射不到實體

項目結構

application.yml

mybatis:
  #映射實體位置
  #若是mapper.xml放在resources中能夠生效
  #若是mapper.xml放在dao接口的包中不生效
  type-aliases-package: cn.***.pojo
  #若是mapper.xml文件放在resources中須要下面這行配置，若是和dao接口放在一個包中不須要
  #  mapper-locations: classpath:mybatis/mapper/*.xml

TestDataSource1

    若是mapper.xml文件放在和dao一個包中必定要加入bean.setTypeAliasesPackage("cn.***.pojo")，否則映射不到實體

@Configuration // 註冊到springboot容器中
@MapperScan(basePackages = "cn.***.dao", sqlSessionFactoryRef = "test1SqlSessionFactory")
public class TestDataSource1 {

    /**
     * @methodDesc: 功能描述:(配置test1數據庫)
     */
    @Bean(name = "test1DataSource")
    @ConfigurationProperties(prefix = "spring.datasource.test1")//把同類的配置信息自動封裝成實體類
    @Primary//自動裝配時當出現多個Bean候選者時，被註解爲@Primary的Bean將做爲首選者，不然將拋出異常
    public DataSource testDataSource() {
        return DataSourceBuilder.create().build();
    }

    /**

        // bean.setMapperLocations(

    }

TestDataSource1

    若是mapper.xml文件放在和dao一個包中必定要加入bean.setTypeAliasesPackage("cn.***.pojo")，否則映射不到實體

@Configuration // 註冊到springboot容器中
@MapperScan(basePackages = "cn.***.dao1", sqlSessionFactoryRef = "test2SqlSessionFactory")
public class TestDataSource2 {
    /**
     *
     * @methodDesc: 功能描述:(配置test2數據庫)
     */
    @Bean(name = "test2DataSource")
    @ConfigurationProperties(prefix = "spring.datasource.test2")//把同類的配置信息自動封裝成實體類

    public DataSource testDataSource() {
        return DataSourceBuilder.create().build();
    }

    /**
     *
     * @methodDesc: 功能描述:(test2 sql會話工廠)

     */
    @Bean(name = "test2SqlSessionFactory")
    public SqlSessionFactory testSqlSessionFactory(@Qualifier("test2DataSource") DataSource dataSource)
            throws Exception {
        SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
        bean.setDataSource(dataSource);
        //若是mapper和dao放在一個包中須要mybatis實體映射
        bean.setTypeAliasesPackage("cn.***.pojo");
        // bean.setMapperLocations(
        // new
        // PathMatchingResourcePatternResolver().getResources("classpath:mybatis/mapper/test2/*.xml"));
        return bean.getObject();
    }

    /**

     * @methodDesc: 功能描述:(test2 事物管理)
     */
    @Bean(name = "test2TransactionManager")
    public DataSourceTransactionManager testTransactionManager(@Qualifier("test2DataSource") DataSource dataSource) {
        return new DataSourceTransactionManager(dataSource);
    }

    @Bean(name = "test2SqlSessionTemplate")
    public SqlSessionTemplate testSqlSessionTemplate(
            @Qualifier("test2SqlSessionFactory") SqlSessionFactory sqlSessionFactory) throws Exception {
        return new SqlSessionTemplate(sqlSessionFactory);
    }

pom.xml

    若是想將mapper.xml和和dao接口放在一個包中須要在pom中的<build>標籤中加入以下配置

    若是mapper.xml放在resource資源文件中，pom中不須要配置。

    緣由：編譯器會默認到resources資源文件中尋找配置文件
