I want to map a DTO (all are of String Data Types) to VO (contains String,int,boolean,Date) StudentDTO private StudentDetailDTO student; StudentDetailDTO : private String sid; private String name; private String createDt; private String studentInd; private List<FeeReceiptDTO> feeDetails; FeeReceiptDTO: private String semisterNum; private String feeAmount; private String paidOn; StudentDetailVO : private int sid; private String name; private Date createDt; private boolean studentInd; private List<FeeReceiptVO> feeDetails; FeeReceiptVO: private int semisterNum; private Double feeAmount; private

Dozer Dozer 是一个映射框架，它使用递归将数据从一个对象复制到另一个对象。框架不仅能够在 bean 之间复制属性，还能够在不同类型之间自动转换。 要使用 Dozer 框架，我们需要添加这样的依赖到我们的项目: <dependency> <groupId>net.sf.dozer</groupId> <artifactId>dozer</artifactId> <version>5.5.1</version> </dependency> 更多关于 Dozer

We're to use DTO's to send data to and from the presentation layer. We have layers like: facade appService domain And We have use Dozer to help us convert entity to dto. But i have 2 question now: from entity to dto we can use dozer, but from dto to entity can we use dozer? If Yes, How? Where shoud i create entity? in facade or DTOAssembler? for example,I have to register a book. the book Entity look's like: Book{ public Book(BookNumber number,String name){ //make sure every book has a business number, //and the number can't change once the book is created. this.bookNumber = number; .. } } and

I am using Dozer to map between a Document class to DocumentManagementBean class, both of my own making. Both have a property, with getters and setters, of Joda DateTime type, called dateAdded. When Document object d has property dateAdded =x, calling mapper.map(d, DocumentManagementBean.class) all fields get auto-mapped correctly (since I have full control over code base I am able to get away with no dozer-config and rely simply on matching property names), EXCEPT the dateAdded field, where the new DocumentManagementBean dmb ends up with the current DateTime in its dateAdded property, instead

I have such enum: public enum PartnershipIndicator { VENDOR("VENDOR"), COPARTNER("COPARTNER"), BUYER("BUYER"); String code; private PartnershipIndicator(String code) { this.code = code; } public String getCode() { return code; } public static PartnershipIndicator valueOfCode(String code) { for (PartnershipIndicator status : values()) { if (status.getCode().equals(code)) { return status; } } throw new IllegalArgumentException( "Partnership status cannot be resolved for code " + code); } @Override public String toString() { return code; } } I need to convert it to String and vice versa. Now, it

EDIT : A new lib has been introduced which clarify the thing for new versions Since version 5.5.0 Spring integration comes within additional module dozer-spring. Hi there I'm relatively new to Dozer and Spring and a bit confused about how to put that in place. From the dozer website : http://dozer.sourceforge.net/documentation/usage.html Spring integration ... <bean id="mapper" class="org.dozer.DozerBeanMapper"> <property name="mappingFiles"> <list> <value>dozer-global-configuration.xml</value> <value>dozer-bean-mappings.xml</value> <value>more-dozer-bean-mappings.xml</value> </list> <

Suppose I have the following classes public class Baz { private List<Foo> foos = new ArrayList<Foo>(); } public class Foo { private String string; } public class Target { private List<String> fooStrings = new ArrayList<String>(); } Is there any mapping I can use to, given a Baz, map it to the target class and get a list of the strings contained within the foo's in Baz? The following mapping does not work <mapping> <class-a>Baz</class-a> <class-b>Target</class-b> <field> <a>foos.string</a> <b>fooStrings</b> </field> </mapping> Because string is not a property of foos (which is of type List). I
