今天完成的事情：druid监控实现：

@Configuration

public class DruidConfig {

        servletRegistrationBean.addInitParameter("allow", "183.192.36.131,127.0.0.1");

        return filterRegistrationBean;

    }

    @Bean

    PersistenceExceptionTranslationPostProcessor persistenceExceptionTranslationPostProcessor() {

        return new PersistenceExceptionTranslationPostProcessor();

    }

    //配置数据库的基本链接信息

    @Bean(name = "dataSource")

    @Primary

    @ConfigurationProperties(prefix = "spring.datasource")    //可以在application.properties中直接导入

    public DataSource dataSource() {

        return DataSourceBuilder.create().type(com.alibaba.druid.pool.DruidDataSource.class).build();

    }

    @Bean

    public SqlSessionFactory SqlSessionFactory(@Qualifier("dataSource") DataSource dataSource)

            throws Exception {

        final SqlSessionFactoryBean sessionFactory = new SqlSessionFactoryBean();

        sessionFactory.setDataSource(dataSource);

        //这里不方便改，干脆在mapper文件里面写全名得了

        //sessionFactory.setTypeAliasesPackage("com.ptteng.domain");

        sessionFactory.setMapperLocations(new PathMatchingResourcePatternResolver()

                .getResources("classpath:mapper/*.xml"));

        sessionFactory.setConfigLocation(

                new DefaultResourceLoader().getResource("classpath:mybatis/mybatis-config.xml"));

        return sessionFactory.getObject();

    }

}

 
明天计划的事情：继续学习boot 
遇到的问题：druid整合log4j2 
收获：熟悉了boot的配置方式，@configuration类
