Dozerbeanmapper + Object Transfer Map method

1. Introduction
Dozer is a JavaBean mapping tool, similar to the Apache Beanutils. But Dozer is more powerful, it can handle the mapping between complex types flexibly. Not only can simple attribute mapping, complex type mapping, bidirectional mapping, recursive mapping and so on, and can be flexibly configured through XML configuration file.

2. Preparation
Let's try it out for a little bit now.
First, you need to download the jar package,
Dozer.jar:http://dozer.sourceforge.net/downloading.html
We need Slf4j.jar,commons-lang.jar,commons-beanutil.jar, Commons-loggin.jar.

Java code

2. Import com.google.common.collect.Lists;
4. Import java.util.Collection;
6. Import Java.util.Iterator;
8. Import java.util.List;
10. Import Org.dozer.DozerBeanMapper;
14. Public class Beanmapper
16. {
18. private static Dozerbeanmapper dozer = new Dozerbeanmapper ();
22. /** 
24. * Constructs a new Destinationclass instance object, through the contents of the field in the source object
26. * Map to the Destinationclass instance object and return the new Destinationclass instance object.
28. *
30. * @param source data Object
32. * @param destinationclass to construct a new instance object class
34. */
36. public static <T> T map (Object source, class<t> Destinationclass)
38. {
40. return Dozer.map (source, Destinationclass);
42. }
50. public static <T> list<t> maplist (Collection sourceList, class<t> destinationclass)
52. {
54. List destinationlist = Lists.newarraylist ();
56. For (Iterator i$ = Sourcelist.iterator (); I$.hasnext ();)  {Object sourceObject = I$.next ();
58. Object destinationobject = Dozer.map (SourceObject, Destinationclass);
60. Destinationlist.add (Destinationobject);
62. }
64. return destinationlist;
66. }
72. /** 
74. * Copy all the property values of the object source into the object destination.
76. *
78. * @param source Object source
80. * @param Destination Object destination
82. */
84. public static void Copy (object source, Object Destinationobject)
86. {
88. Dozer.map (source, destinationobject);
90. }
92. }

Use:

Java code

2. Smiaasquotav result = null;
4. try {
6. result = Limitservice.getlimitdetails (Id,parentid);
8. if (Result! = null) {
10. Response.setdata (Beanmapper.map (result, map.   Class));
12. Response.setsuccess (true);
14. }
16. }

Beanmapper.map (result, Map.class)

Convert to a Map object.

Java code

2. Public static <T> map<string, t> tomap (Object target) {
4. return Tomap (target,false);
6. }
10. /**
12. * Convert all properties of the target object to a Map object
14. *
16. * @param target Object
18. * @param ignoreparent whether to ignore the properties of the parent class
20. *
22. * @return Map
24. */
26. Public static <T> map<string, t> tomap (Object target,boolean ignoreparent) {
28. return Tomap (Target,ignoreparent,false);
