    copied!<p>I'm using <em>ObjectMapper</em> to do my java-json mapping.</p> <pre><code>ObjectWriter ow = new ObjectMapper().writer().withDefaultPrettyPrinter(); ow.writeValue(new File( fileName +".json"), jsonObj); </code></pre> <p>this is my java class:</p> <pre><code>public class Relation { private String id; private String source; private String target; private String label; private List&lt;RelAttribute&gt; attributes; public String getId() { return id; } public void setId(String id) { this.id = id; } public String getSource() { return source; } public void setSource(String source) { this.source = source; } public String getTarget() { return target; } public void setTarget(String target) { this.target = target; } public String getLabel() { return label; } public void setLabel(String label) { this.label = label; } public void setAttributes(List&lt;RelAttribute&gt; attributes) { this.attributes = attributes; } public List&lt;RelAttribute&gt; getAttributes() { return attributes; } } </code></pre> <p>this is what I get:</p> <pre><code>{ "id" : "-75da69d3-79c8-4000-a3d8-b10350a57a7e", "attributes" : [ { "attrName" : "ID", "attrValue" : "" }, { "attrName" : "Description", "attrValue" : "Primary Actor" }, { "attrName" : "Status", "attrValue" : "" } ], "label" : "new Label", "target" : "-46b238ac-b8b3-4230-b32c-be9707f8b691", "source" : "-daa34638-061a-45e0-9f2e-35afd6c271e0" } </code></pre> <p>So my question now is, how can I get this json output:</p> <pre><code>{ "id" : "-75da69d3-79c8-4000-a3d8-b10350a57a7e", "label" : "new Label", "target" : "-46b238ac-b8b3-4230-b32c-be9707f8b691", "source" : "-daa34638-061a-45e0-9f2e-35afd6c271e0", "attributes" : [ { "attrName" : "ID", "attrValue" : "" }, { "attrName" : "Description", "attrValue" : "Primary Actor" }, { "attrName" : "Status", "attrValue" : "" } ] } </code></pre> <p>I want it with same order as in my java declaration. Is there a way to specify it ? Maybe with annotations or stuff like that ?</p>
