- 首先，MyBatis生成插入语句时，需要获取每个字段的vlaue和jdbcType。
- value通过参数传入，jdbcType则来自在Mapper中的显式声明。
- 假如某字段的value为null，Mapper中也未为其声明jdbcType，MyBatis将从org.apache.ibatis.session.Configuration对象中的jdbcTypeForNull拿来作为当前字段的jdbcType，而jdbcTypeForNull的默认值为，JdbcType.OTHER。
- 将这个JdbcType.OTHER传入后续的映射逻辑，由于Oracle驱动中，没有与之对应的映射关系，所以，就会报错。
- 若预判某字段可能为null，则需要在Mapper的SQL中显式声明其jdbcType。
可以以此方法为入口（带3个问号的行注释，代表主要方法，会在下文一并贴出）
org.apache.ibatis.scripting.defaults.DefaultParameterHandler#setParameters
public void setParameters(PreparedStatement ps) throws SQLException {
ErrorContext.instance().activity("setting parameters").object(this.mappedStatement.getParameterMap().getId());

if (parameterMappings != null) {
MetaObject metaObject = this.parameterObject == null ? null : this.configuration.newMetaObject(this.parameterObject);
for(int i = 0; i < parameterMappings.size(); ++i) {
ParameterMapping parameterMapping = (ParameterMapping)parameterMappings.get(i);
if (parameterMapping.getMode() != ParameterMode.OUT) {
String propertyName = parameterMapping.getProperty();
Object value;
if (this.boundSql.hasAdditionalParameter(propertyName)) {
value = this.boundSql.getAdditionalParameter(propertyName);
} else if (this.parameterObject == null) {
value = null;
} else if (this.typeHandlerRegistry.hasTypeHandler(this.parameterObject.getClass())) {

} else {

}

// 1.从Mapper中获取当前字段的jdbcType

// 2.value为null，且Mapper中的jdbcType也为null（一般是未声明），则获取configeration中的jdbcTypeForNull
if (value == null && jdbcType == null) {

}

}
}
}
}

throw new TypeException("JDBC requires that the JdbcType must be specified for all nullable parameters.");

}
} else {
this.setNonNullParameter(ps, i, parameter, jdbcType);
}
}
以Oracle的jdbc实现为例，
jdbcType和数据库厂商的字段类型，都是以数字编码来表示的，于是jdbc标准和厂商之间就需要实现映射；以下逻辑就是为了完成MyBatis中定义的jdbcType向Oracle数据类型的映射。
