Examples of org.soybeanMilk.core.bean.DefaultGenericConverter

org.soybeanMilk.core.bean.DefaultGenericConverter

默认通用转换器的。

它支持的类型转换如下所示：

源类型	目标类型
String	boolean, Boolean; byte, Byte; char, Character; double, Double; float, Float; int, Integer; long, Long; short, Short; java.math.BigDecimal; java.math.BigInteger; java.util.Date; java.sql.Date; java.sql.Time; java.sql.Timestamp; enum
String[]	上述各类型的数组、java.util.List、java.util.Set。比如“int[]”、“boolean[]”、“Short[]”、List<Integer>、List<Date>、Set<Integer>、Set<Date>
Map<String, ?>	JavaBean; List<JavaBean>; Set<JavaBean>; Map<SomeKeyType, JavaBean>

对于Map<String, ?>类型的源对象，它的关键字必须符合下面的访问符表达式格式：

accessor[.accessor ...]

这里，accessor可以是下面这些语义和字面值：

JavaBean对象属性名
表明映射表的值是JavaBean的accessor属性值
List、Set、数组对象的下标值
表明映射表的值是某个集合第accessor个元素的值
Map对象关键字
表明映射表的值是另一个映射表accessor关键字的值
"class"字面值
指定自定义转换目标类型，用以提供多态转换支持，它的值必须是全类名，比如：
"class" -> "org.somePkg.SomeJavaBean"
    指定转换目标类型为“org.somePkg.SomeJavaBean”
"2.class" -> "org.somePkg.SomeJavaBeanSub"
    指定转换目标集合的第三个元素类型为“org.somePkg.SomeJavaBeanSub”
"someKey.class" -> "org.somePkg.SomeJavaBean"
    指定转换目标映射表的"someKey"元素类型为“org.somePkg.SomeJavaBean”
"classes"字面值
当转换目标为集合类时（数组、List、Set），用以统一设置元素类型的数组，比如：
"classes" -> ["org.somePkg.SomeJava", "org.somePkg.SomeJavaSub"]
"2.class" -> "org.somePkg.SomeJavaBean"
指定目标集合的第一个元素类型为“org.somePkg.SomeJava”，第二个元素类型为“org.somePkg.SomeJavaSub”，第三个元素类型为“org.somePkg.SomeJavaBean”

比如，它可以将下面的映射表：

 "id"                    ->  "1" "name"                  ->  "jack" "listChildren.id"       ->  ["11", "12"] "listChildren.name"     ->  ["tom", "mary"] "setChildren.id"        ->  ["11", "12"] "setChildren.name"      ->  ["tom", "mary"] "arrayChildren.id"      ->  ["11", "12"] "arrayChildren.name"    ->  ["tom", "mary"] "mapChildren.key0.id"   ->  "11" "mapChildren.key0.name" ->  "tom" "mapChildren.key1.id"   ->  "22" "mapChildren.key1.name" ->  "mary"

转换为：

 package org.somePkg; class User{ private Integer id; private String name; private List<User> listChildren; private Set<User> setChildren; private User[] arrayChildren; private Map<String, User> mapChildren; ... }

类型的对象，或者将：

 "id"                             ->  ["1","2","3"] "name"                           ->  ["jack","tom","cherry"] "0.listChildren.id"              ->  ["10","11"] "0.listChildren.name"            ->  ["jack10","jack11"] "1.setChildren.0.id"             ->  "20" "1.setChildren.0.name"           ->  "tom20" "1.setChildren.1.id"             ->  "21" "1.setChildren.1.name"           ->  "tom21" "2.arrayChildren.0.id"           ->  "30" "2.arrayChildren.0.name"         ->  "cherry30" "2.arrayChildren.1.id"           ->  "31" "2.arrayChildren.1.name"         ->  "cherry31" "2.mapChildren.key0.id"          ->  "30" "2.mapChildren.key0.name"        ->  "cherry30" "2.mapChildren.key1.id"          ->  "31" "2.mapChildren.key1.name"        ->  "cherry31"

转换为：

 List<User> Set<User> User[]

类型的对象。

你也可以通过 {@linkplain #addConverter(Type,Type,Converter)}方法为它添加更多辅助转换器，使其支持更多的类型转换。
另外，如果目标类型为String，而你没有添加某类型对象到String类型的辅助转换器，那么它将返回此对象的toString()结果。
