Functions

func AopProxyService 

func AopProxyService(service interface{}, engine SessionEngine)

使用AOP切面 代理目标服务，如果服务painc()它的事务会回滚 默认为单协程模型，如果是多协程调用的情况请开启engine.SetGoroutineIDEnable(true)

func AopProxyServiceValue 

func AopProxyServiceValue(service reflect.Value, engine SessionEngine)

使用AOP切面 代理目标服务，如果服务painc()它的事务会回滚

func CreateXml 

func CreateXml(tableName string, bean interface{}) []byte

* //例子

//GoMybatis当前是以xml内容为主gm:""注解只是生成xml的时候使用 //定义数据库模型, gm:"id"表示输出id的xml,gm:"version"表示为输出版本号的xml，gm:"logic"表示输出逻辑删除xml 

type TestActivity struct {
	Id         string    `json:"id" gm:"id"`
	Uuid       string    `json:"uuid"`
	Name       string    `json:"name"`
	PcLink     string    `json:"pcLink"`
	H5Link     string    `json:"h5Link"`
	Remark     string    `json:"remark"`
	Version    int       `json:"version" gm:"version"`
	CreateTime time.Time `json:"createTime"`
	DeleteFlag int       `json:"deleteFlag" gm:"logic"`
}

func TestUserAddres(t *testing.T)  {
	var s=utils.CreateDefaultXml("biz_user_address",TestActivity{})//创建xml内容
	utils.OutPutXml("D:/GOPATH/src/dao/ActivityMapper.xml",[]byte(s))//写入磁盘
}

根据结构体 创建xml文件

func LoadMapperXml 

func LoadMapperXml(bytes []byte) (items map[string]etree.Token)

func OutPutXml 

func OutPutXml(fileName string, body []byte)

输出文件

func Proxy 

func Proxy(proxyPtr interface{}, buildFunc func(funcField reflect.StructField, field reflect.Value) func(arg ProxyArg) []reflect.Value)

AopProxy 可写入每个函数代理方法.proxyPtr:代理对象指针，buildFunc:构建代理函数

func ProxyValue 

func ProxyValue(mapperValue reflect.Value, buildFunc func(funcField reflect.StructField, field reflect.Value) func(arg ProxyArg) []reflect.Value)

AopProxy 可写入每个函数代理方法

func SnakeString 

func SnakeString(s string) string

转蛇形命名snake string, XxYy to xx_yy , XxYY to xx_yy

func StructToSnakeString 

func StructToSnakeString(arg interface{}) string

结构体名称转蛇形名称 例如 pcLink = pc_link

func WriteMapper 

func WriteMapper(bean reflect.Value, xml []byte, sessionEngine SessionEngine)

写入方法内容，例如 

type ExampleActivityMapperImpl struct {
	SelectAll         func(result *[]Activity) error
	SelectByCondition func(name string, startTime time.Time, endTime time.Time, page int, size int, result *[]Activity) error `mapperParams:"name,startTime,endTime,page,size"`
	UpdateById        func(session *GoMybatis.Session, arg Activity, result *int64) error                                     //只要参数中包含有*GoMybatis.Session的类型，框架默认使用传入的session对象，用于自定义事务
	Insert            func(arg Activity, result *int64) error
	CountByCondition  func(name string, startTime time.Time, endTime time.Time, result *int) error `mapperParams:"name,startTime,endTime"`
}

func的基本类型的参数（例如string,int,time.Time,int64,float....）个数无限制(并且需要用Tag指定参数名逗号隔开,例如`mapperParams:"id,phone"`)，返回值必须有error func的结构体参数无需指定mapperParams的tag，框架会自动扫描它的属性，封装为map处理掉 使用WriteMapper函数设置代理后即可正常使用。

func WriteMapperByValue 

func WriteMapperByValue(value reflect.Value, xml []byte, sessionEngine SessionEngine)

推荐默认使用单例传入 根据sessionEngine写入到mapperPtr，value:指向mapper指针反射对象，xml：xml数据，sessionEngine：session引擎，enableLog:是否允许日志输出，log：日志实现

func WriteMapperPtrByEngine 

func WriteMapperPtrByEngine(ptr interface{}, xml []byte, sessionEngine SessionEngine)

推荐默认使用单例传入 根据sessionEngine写入到mapperPtr，ptr:指向mapper指针，xml：xml数据，sessionEngine：session引擎，enableLog:是否允许日志输出，log：日志实现
