Problem with xml characters escaping in spring soap request object

Question

I use spring web services and i want to send soap request via WebServiceTemplate, but the object to send contains a string with <, > character and these characters got escaped as bellow :

<![CDATA[<greeting>Hello, world!</greeting>]]>

But i want the result to be :

<![CDATA[<greeting>Hello, world!</greeting>]]>

Here is my soap config :

  @Bean
    public Jaxb2Marshaller marshaller() {
        Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
        marshaller.setContextPath("packageName");
        Map<String, Object> props = new HashMap<>();
        props.put(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        CharacterEscapeHandler escapeHandler = NoEscapeHandler.theInstance;
        props.put("com.sun.xml.bind.characterEscapeHandler", escapeHandler);
        props.put("com.sun.xml.bind.marshaller.CharacterEscapeHandler", escapeHandler);
        props.put(Marshaller.JAXB_ENCODING, "utf-8");
        marshaller.setMarshallerProperties(props);
        return marshaller;
    }

    @Bean
    public SoapClient soapClient(@Value("${soap.url}") String url) {
        SoapClient client = new SoapClient();
        client.setDefaultUri(url);
        client.setMarshaller(marshaller());
        client.setUnmarshaller(marshaller());
        return client;
    }

How can i get the result with <, > character, without escaping ? I need your help please!
