I have classes, which have not public constructor (dicts, project started write in java 1.4, where there was no enum).
@SpringContextAvailableDict(alias="a")
public class Class1 extends Dict<Object> {
protected String code;
protected String title;
public final static Class1 NULL = new Class1(null, null, Dict.NAME_NULL);
public final static Class1 FOO = new Class1("0", "e", "name1");
public final static Class1 BAR = new Class1("1", "j", "name2",);
private Class1(String code, String letterCode, String title) {
this.code = code;
this.title = title;
}
}
I want to initialize the beans like
<bean parent="dict-wrapper-value" p:value="a_FOO"/>
I was create the class
public class StringToDictConverter extends PropertyEditorSupport {
protected Map<String, Class<?>> dicts = new HashMap<String, Class<?>>();
public StringToDictConverter() throws ClassNotFoundException{
ClassPathScanningCandidateComponentProvider scanner
= new ClassPathScanningCandidateComponentProvider(false);
scanner.addIncludeFilter(
new AnnotationTypeFilter(SpringContextAvailableDict.class));
for (BeanDefinition bd : scanner.findCandidateComponents("exmpl/*")){
// puting bd's class to dicts on key annotation parament 'alias';
}
}
@Override
public void setAsText(String text) throws IllegalArgumentException {
String[] name = text.split("_", 2);
setValue(dicts.get(name[0]).getField(name[1]).get(new Object()))
}
}
what convert string开发者_运维知识库 to dict, using dict's class, but I want get class description using spring xml config like <context:annotation-config/
>, but <context:annotation-config/
> trying to get instance of class and it has not public constructor.
You can not simply create an instance of this class. You need a (Spring) Factory to create the objects.
