defaultSqlSession有指定的configuration

9.   等11走完直接返回config

SecuritySupport

getSystemProperty(final String propName)

UserMapper mapper = sqlSession.getMapper(UserMapper.class);

XPathFactory

DEFAULT_OBJECT_MODEL_UR

newInstance()；newInstance(DEFAULT_OBJECT_MODEL_URI);

自定义的Mapper.class

null

new XMLMapperEntityResolver()

10.2

true

MapperProxyFactory<T>

(MapperProxyFactory<T>) V get(Object key);T newInstance(SqlSession sqlSession)  protected T newInstance(MapperProxy<T> mapperProxy)

XMLConfigBuilder

private final XPathParser parser;

AccessController

doPrivileged(PrivilegedAction<T> action)

XPathParser

  private final Document document; private boolean validation; private EntityResolver entityResolver; private Properties variables; private XPath xpath;

10.1

SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(                UserTest.class.getClassLoader().getResourceAsStream(\"mybatis-config.xml\"));

13  将config传进新类

XPathFactoryFinder

XPathFactory newFactory(String uri) private XPathFactory _newFactory(String uri)  XPathFactory createInstance(String className)

Configuration

MapperRegistry mapperRegistry = new MapperRegistry(this);

DefaultSqlSessionFactory implements SqlSessionFactory

DefaultSqlSessionFactory(config)

这个方法通过类的全路径进行反射来获取实例

SqlSession sqlSession = sqlSessionFactory.openSession(true);

17  config传进去
