CXF学习(4) 处理无法自动转换的复合数据类型

只贴出服务端代码

1.Service接口类

package com.test.hello;

import java.util.Map;

import javax.jws.WebService;
import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter;

import com.test.util.MineAdapter;

@WebService
public interface HelloWorld {
//    public void sayHello();
    //cxf 不能处理 map 类型,于是我们采用MineAdapter.class进行处理
    public @XmlJavaTypeAdapter(MineAdapter.class) Map<String,Cat> getMap();
}

2.服务实现类

package com.test.hello;

import java.util.HashMap;
import java.util.Map;

import javax.jws.WebService;

@WebService(endpointInterface="com.test.hello.HelloWorld",serviceName="HelloWorldWS")
public class HelloWorldImpl implements HelloWorld{

    private static Map<String,Cat> map;
    static {
        map = new HashMap<String, Cat>();
        map.put("tomcat", new Cat());
        map.put("garfield", new Cat());
    }

    public Map<String,Cat> getMap() {
        return map;
    }

}

Cat类

package com.test.hello;

public class Cat {
    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

StringCat

package com.test.util;

import java.util.ArrayList;
import java.util.List;

import com.test.hello.Cat;

public class StringCat {

    public static class Entry {
        private String key;
        private Cat value;
        public Entry(String key, Cat value) {
            this.key=key;
            this.value=value;
        }
        public String getKey() {
            return key;
        }
        public void setKey(String key) {
            this.key = key;
        }
        public Cat getValue() {
            return value;
        }
        public void setValue(Cat value) {
            this.value = value;
        }
    }
    private List<Entry> entries = new ArrayList<StringCat.Entry>();
    public List<Entry> getEntries() {
        return entries;
    }
    public void setEntries(List<Entry> entries) {
        this.entries = entries;
    }
    @Override
    public String toString() {
        StringBuilder str = null;
        for (Entry entry : entries) {
            str.append(entry.getKey() +" : "+entry.getValue());
        }
        return str.toString();
    }
}

这是重点，适配器类

package com.test.util;

import java.util.HashMap;
import java.util.Map;

import javax.xml.bind.annotation.adapters.XmlAdapter;

import com.test.hello.Cat;
import com.test.util.StringCat.Entry;

//改转换器就负责完成StringCat与Map的相互转换
public class MineAdapter extends XmlAdapter<StringCat, Map<String,Cat>>{

    @Override
    public Map unmarshal(StringCat strngCat) throws Exception {
        Map result = new HashMap();
        for(Entry entry : strngCat.getEntries()){
            result.put(entry.getKey(),entry.getValue());
        }

        return result;
    }

    @Override
    public StringCat marshal(Map<String,Cat> map) throws Exception {
        StringCat stringCat = new StringCat();
        for (String key : map.keySet()) {
            stringCat.getEntries().add(new Entry(key,map.get(key)));
        }
        return stringCat;
    }
}

最后是运行类

package com.test.hello;

import javax.xml.ws.Endpoint;

public class ServerMain {
    public static void main(String[] args) {
        HelloWorld helloWorldImpl = new HelloWorldImpl();
        Endpoint.publish("http://localhost:1234/ws", helloWorldImpl);
        System.out.println("webservice 暴露成功");
    }
}
