@ElementMap problem with composite values

[hoomanv]

There is no way I can parse the following xml using ElementMap

<dataSources>
    <dataSource name="a">
        <url>http://host1/</url>
    </dataSource>
    <dataSource name="b">
        <url>http://host2/</url>
    </dataSource>
</dataSources>

ElementMap forces me to change the structure of the xml to something like this:

<dataSources>
    <entry name="a">
        <dataSource name="a">
            <url>http://host1/</url>
        </dataSource>
    </entry>
    <entry name="b">
        <dataSource name="b">
            <url>http://host2/</url>
        </dataSource>
    </entry>
</dataSources>

It seems the only way to parse the orignal xml is to use ElementList and convert it to Map manually. Tell me if I'm wrong please

Can you post your Java classes?

Why not try using @ElementList(inline=true)

[hoomanv]

It works with ElementList as I said. But I want a java.util.Map not a List

class Config
{
    @ElementMap(entry = "dataSources", attribute = true, key = "name")
    private Map<String, DataSource> dataSources;
}

class DataSource
{
    @Attribute
    String name;

    @Element
    String url;
}

I played with all permutations you can think of with ElementMap's attributes but nothing worked.

Try this

class Config
{
    @ElementMap(name = "dataSources", attribute = true, inline = true, key = "name")
    private Map<String, DataSource> dataSources;
}

I have a structure something like this, but for @ElementList

@Root(name="dataSources")
class Config
{
    @ElementMap(attribute = true, inline = true, key = "name")
    private Map<String, DataSource> dataSources;
}

See if either solution works.

I have tried it before.

@Root(name="dataSources")
public class Config
{
    @ElementMap(attribute = true, inline = true, key = "name")
    public Map<String, DataSource> dataSources;
}

@Root(name = "dataSource")
public class DataSource
{
    @Attribute
    public String name;

    @Element
    public String url;
}

Above classes will not parse this

<dataSources>
    <dataSource name="a">
        <url>a</url>
    </dataSource>
</dataSources>

but will parse this

<dataSources>
    <dataSource name="a">
        <dataSource name="a">
            <url>a</url>
        </dataSource>
    </dataSource>
</dataSources>

First: I need a map of <String, DataSource> not <String, String>.

Second: You mentioned @ElementMap(... value="url" ...) What if dataSource was like this

<dataSource name="...">
    <url>...</url>
    <user>...</user>
    <pass>...</pass>
</dataSource>

It is with the composite types that breaks the code.

I don't think @ElementMapUnion will be of any help in this case. Can you provide a sample code that works exactly with this xml

<dataSources>
    <dataSource name="...">
        <url>...</url>
        <user>...</user>
    </dataSource>
</dataSources>

And read it in a Map<String, DataSource> using either ElementMap or ElementMapUnion? I appreciate if you take your time to test it yourself

It looks that I have very similar problem http://stackoverflow.com/questions/36366430/list-as-value-of-map Any maybe this is also the same problem http://stackoverflow.com/questions/9058477/right-usage-of-org-simpleframework-xml-elementmap
