将Json转实体

Posted 2020-10-23 Ice_Blue_Brother

算了，不废话了

protected static ObjectMapper mapper = new ObjectMapper();

 

//转一个
public <S> S getRequestParams(String json, Class<S> membersClazzs)
　　throws JsonParseException, JsonMappingException, IOException {
　　return mapper.readValue(json, membersClazzs);
}

//转多个
public static <S> S getRequestParams(String json, Class<?> collectionsClass,
　　Class<?>... membersClazzs) throws JsonParseException,
　　JsonMappingException, IOException {
　　return mapper.readValue(json, mapper.getTypeFactory().constructParametricType(collectionsClass, membersClazzs));
}

//调用转换方法
public voidTest(@RequestParam("entityJSON") StringentityJSON,……){
　　……
　　Entity entity= getRequestParams(entityJSON,Entity.class);
　　……
}
