@Body

<p>
	The {@link oaj.http.annotation.Body @Body} annotation can be applied to arguments of <ja>@RemoteMethod</ja>-annotated methods
	to denote that they are the HTTP body of the request.
</p>
<ul class='javatree'>
	<li class='ja'>{@link oaj.http.annotation.Body}
	<ul>
		<li class='jf'>{@link oaj.http.annotation.Body#required() required} - Input validation.  Body must be present.
		<li class='jf'>{@link oaj.http.annotation.Body#schema() schema} - Swagger schema.
	</ul>
</ul>

<h5 class='figure'>Examples:</h5>
<p class='bpcode w800'>
	<jc>// Used on parameter</jc>
	<ja>@Remote</ja>(path=<js>"/petstore"</js>)
	<jk>public interface</jk> PetStore {

		<ja>@RemoteMethod</ja>(path=<js>"/pets"</js>)
		String addPet(<ja>@Body</ja> Pet pet);
	}
</p>
<p class='bpcode w800'>
	<jc>// Used on class</jc>
	<ja>@Remote</ja>(path=<js>"/petstore"</js>)
	<jk>public interface</jk> PetStore {

		String addPet(Pet pet);
	}

	<ja>@Body</ja>
	<jk>public class</jk> Pet {...}
</p>

<p>
	The argument can be any of the following types:
</p>
<ul class='spaced-list'>
	<li>
		Any serializable POJO - Converted to output using the {@link oaj.serializer.Serializer} registered with the <c>RestClient</c>.
		<br><c>Content-Type</c> is set to that of the <c>Serializer</c>.
	<li>
		{@link java.io.Reader} - Raw contents of {@code Reader} will be serialized to remote resource.
		<br><c>Content-Type</c> is set to <js>"text/plain"</js>.
	<li>
		{@link java.io.InputStream} - Raw contents of {@code InputStream} will be serialized to remote resource.
		<br><c>Content-Type</c> is set to <js>"application/octet-stream"</js>.
	<li>
		<c>NameValuePairs</c> - Converted to a URL-encoded FORM post.
		<br><c>Content-Type</c> is set to <js>"aplication/x-www-form-urlencoded"</js>.
	<li>
		<c>HttpEntity</c> - Bypass Juneau serialization and pass HttpEntity directly to HttpClient.
</ul>
 
<p>
	OpenAPI schema based serialization can be used by using the {@link oaj.oapi.OpenApiSerializer} class.
</p>

	See {@doc juneau-marshall.OpenApiDetails.Serializers} for information about supported data types in OpenAPI serialization.

<p>
	If your <c>RestClient</c> class does not have a serializer associated with it, the body will automatically be serialized to a 
	string using the rules defined in {@doc PojosConveribleToStrings}.
