4.CXF所支持的数据类型

前言：jdk提供了webService，但为什么使用jdk来开发webService相对少呢？

　　一个重要原因就是jdk支持的数据类型相对不足，例如Map就不为jdk所支持！

CXF支持的数据类型：

　　基本数据类型：

　　　　int、boolean、float等...

　　引用类型：

　　　　String、集合(Set、List、Map)、自定义数据类型...

　　补充说明：cxf支持所有的数据类型！

测试案例：

　　1.构建一个实体类Animals，为了测试基本数据类型，定义了三个属性，int型的id，String的name和float型的price

public class Animals {

    private int id;
    private String name;//动物名称
    private float price;//动物价格
    public Animals() {
        super();
    }
    public Animals(int id, String name, float price) {
        super();
        this.id = id;
        this.name = name;
        this.price = price;
    }
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public float getPrice() {
        return price;
    }
    public void setPrice(float price) {
        this.price = price;
    }
    @Override
    public String toString() {
        return "Animals [id=" + id + ", name=" + name + ", price=" + price
                + "]";
    }
}

　　2.编写SEI以及SEI实现类

@WebService
public interface DataType {
    //添加一个动物
    @WebMethod
    boolean addAnimal(Animals a);
    
    //查找一只动物
    @WebMethod
    Animals findAnimalById(int id);
    
    //查找所有动物(测试List)
    @WebMethod
    List<Animals> findAllAnimals();
    
    //查找所有动物(测试Map)
    @WebMethod
    Map<Integer,Animals> findAllForMap();
}

public class DataTypeImpl implements DataType {

    @Override
    public boolean addAnimal(Animals a) {
        //为方便测试，直接返回true
        return true;
    }

    @Override
    public Animals findAnimalById(int id) {
        return new Animals(1, "car", 50);
    }

    @Override
    public List<Animals> findAllAnimals() {
        List<Animals> list = new ArrayList<Animals>();
        list.add(new Animals(1, "pig", 2000));
        list.add(new Animals(2, "dog", 100));
        list.add(new Animals(3, "duck", 40));
        return list;
    }

    @Override
    public Map<Integer, Animals> findAllForMap() {
        Map<Integer, Animals> map = new HashMap<Integer, Animals>();
        map.put(1, new Animals(1, "rabbit", 20));
        map.put(2, new Animals(1, "chick", 30));
        map.put(3, new Animals(1, "wolf", 20000));
        return map;
    }
}

　　3.发布

public class Publish {

    public static void main(String[] args) {
        String address = "http://localhost:8080/cxfServer";
        Endpoint.publish(address, new DataTypeImpl());
        System.out.println("如果发布成功，打印!");
    }
}

　　4.使用cxf生成客户端代码

　　

　　生成后的结构为：

　　

　　5.查看wsdl文档

　　 6.测试(获取服务端各种数据类型的数据)

public class TestDataType {

    public static void main(String[] args) {
        DataTypeImplService factory = new DataTypeImplService();
        DataType dataType = factory.getDataTypeImplPort();
        
        boolean bool = dataType.addAnimal(new Animals());
        System.out.println(bool);
        
        Animals a = dataType.findAnimalById(1);
        System.out.println(a);
        
        List<Animals> list = dataType.findAllAnimals();
        System.out.println(list);
        
        Return r = dataType.findAllForMap();
        List<FindAllForMapResponse.Return.Entry> entrys = r.getEntry();
        for(Return.Entry entry : entrys){
            int id = (int) entry.getKey();
            Animals name = entry.getValue();
            System.out.println(id+":"+name);
        }
    }
}

运行结果：

true
Animals [id=1, name=car, price=50.0]
[Animals [id=1, name=pig, price=2000.0], Animals [id=2, name=dog, price=100.0], Animals [id=3, name=duck, price=40.0]]
1:Animals [id=1, name=rabbit, price=20.0]
2:Animals [id=1, name=chick, price=30.0]
3:Animals [id=1, name=wolf, price=20000.0]

注意：

map的使用方法略不同，使用dataType.findAllForMap();后，返回的是个Return类，下面是Return类代码：

public class FindAllForMapResponse {

    @XmlElement(required = true)
    protected FindAllForMapResponse.Return _return;

    public FindAllForMapResponse.Return getReturn() {
        return _return;
    }

    public void setReturn(FindAllForMapResponse.Return value) {
        this._return = value;
    }

    @XmlAccessorType(XmlAccessType.FIELD)
    @XmlType(name = "", propOrder = {
        "entry"
    })
    public static class Return {

        protected List<FindAllForMapResponse.Return.Entry> entry;

        public List<FindAllForMapResponse.Return.Entry> getEntry() {
            if (entry == null) {
                entry = new ArrayList<FindAllForMapResponse.Return.Entry>();
            }
            return this.entry;
        }

        @XmlAccessorType(XmlAccessType.FIELD)
        @XmlType(name = "", propOrder = {
            "key",
            "value"
        })
        public static class Entry {

            protected Integer key;
            protected Animals value;

            public Integer getKey() {
                return key;
            }

            public void setKey(Integer value) {
                this.key = value;
            }

            public Animals getValue() {
                return value;
            }

            public void setValue(Animals value) {
                this.value = value;
            }

        }

    }

}
