  1. PODozer String to enum mapping
    text
    copied!<p>I have such enum:</p> <pre><code>public enum PartnershipIndicator { VENDOR("VENDOR"), COPARTNER("COPARTNER"), BUYER("BUYER"); String code; private PartnershipIndicator(String code) { this.code = code; } public String getCode() { return code; } public static PartnershipIndicator valueOfCode(String code) { for (PartnershipIndicator status : values()) { if (status.getCode().equals(code)) { return status; } } throw new IllegalArgumentException( "Partnership status cannot be resolved for code " + code); } @Override public String toString() { return code; } } </code></pre> <p>I need to convert it to String and vice versa. <em>Now, it is done by custom converter.</em> But i want to do it via dozer mappings (if it is possible). If i do not write any mappings to the dozer confing, i get</p> <pre><code>org.dozer.MappingException: java.lang.NoSuchMethodException: by.dev.madhead.demo.test_java.model.PartnershipIndicator.&lt;init&gt;() </code></pre> <p>exception. I cannot add default public constructor to enum, as it is not possible. So, i wrote a trick with internal code and valueOfCode() / toString(). It does not work. Then, i've mapped it in dozer config:</p> <pre><code>&lt;mapping&gt; &lt;class-a&gt;java.lang.String&lt;/class-a&gt; &lt;class-b create-method="valueOfCode"&gt;by.dev.madhead.demo.test_java.model.PartnershipIndicator&lt;/class-b&gt; &lt;/mapping&gt; </code></pre> <p>It does not work. I tried valueOfCode(), one-way mappings. Nothing works. Enum to String conversion does not work too, i get empty Strings. Any ideas?</p>
