EasyObjectUtils 是 EasyCommons 项目组下的对象操作组件。
EasyCommons 一个针对Java开发领域提供通用开发组件的项目。旨在为Java项目开发领域并不完善的一些方面，提供一些组件级的解决方案。 该项目有多个子项目，会不断收集相关组件，也欢迎有新的组件加入。
EasyObjectUtils is EasyCommons project group obejct operations component.
EasyCommons is a development component to provide a common field for Java development projects. Java is designed to develop programs in the field of some aspects of the project is not perfect, some component-level solutions. The project has multiple sub-projects, will continue to collect related components, also welcomed the new components added.
- EasyObjectUtils 核心
- EasyObjectExtract：对象抽取。 从对象中使用字段表达式(
FieldExpression)抽取指定属性以 key-value 存入Map集合。
适合场景：JSON输出时，从对象中抽取指定输出属性和值。
- EasyObjectFilter：JavaBean对象属性过滤。将对象中的特殊字符(<,>,...)全部过滤掉，转为转义符；或者自定义字符转换映射。
适合场景：将JavaBean对象属性中的字符串包含的特殊字符进行过滤转换为字符实体；或将对象字符串属性中包含的字符全部替换为指定字符。例如，在Struts2中文件上传时提交的数据封装到对象后，对对象中可能包含的用户提交的的特殊字符串的进行转义。
- EasyObjectSetNull：对象属性置空。使用字段表达式(
FieldExpression)将对象中指定属性设置为null。
适合场景：将Hibernate加载的对象中有些延迟无法加载的属性设置为空 ，防止在序列化属性时出现no session异常。
- EasyObject FieldExpression（字段表达式）语言 可以在进行对象操作时进行属性定位。
指定属性： property
指定属性的属性：property.property
指定集合中每一个对象： {collection}
指定数组中每一个对象： [array]
指定集合中每一个对象的属性：{collection}.property
指定数组中每一个对象的属性：[array].property
别名定义(仅适用于EasyObjectExtract)：FieldExpression#Alias

- EasyObjectUtils core:
-
EasyObjectExtract: extraction of the object. Using field expression from the object (
FieldExpression) to extract the specified property deposited key-value Map collection.
Scene: JSON output, specify the output attributes and values extracted from the object. -
EasyObjectFilter: JavaBean Object property filtering. The object of special characters (<,>, ...) to filter out, into the escape character; or custom character transformation maps.
Scene : the special character JavaBean Object property contains a string to filter into character entity; or a character string property objects included replacing all the specified character. For example, the data in the file upload Struts2 package submitted to the object, a special string to the user object may contain submitted escaped. -
EasyObjectSetNull: Object Properties empty. Using field expressions Language(
FieldExpression) specified property set to null object.
Scene: Hibernate object loaded some delay attribute set can not be loaded is empty, to prevent abnormal when no session serialized property.
- EasyObject FieldExpression language EasyObjectUtils the tools used to EasyObject FieldExpression (field expression) language for property positioning when you operate object.
Syntax:
Specified attributes: property
Specify the attribute that: property.property
Each object in the specified collection: {collection}
Each object in the specified array: [array] Attribute specifies for each object in the collection: {collection} .property
Attribute specifies for each object in the array: [array] .property
Alias definitions (only for EasyObjectExtract): FieldExpression#Alias
