SpringRoo自定义查找器

好吧，采用老式的方法… Java中的Servlets标准定义了带有参数的Map（哈希，字典）所在的Request对象，因此您可以通过以下方式访问它们：

public ModelAndView searchAssets(HttpRequest request) {    StringBuilder builder = new StringBuilder();    for (String param : request.getParameterNames()) {        value = request.getParameter(param);        builder.append(param);        builder.append("="); // or LIKE        builder.append("'" + value "'");        builder.append(" AND ");    }    // deleting the last " AND "    builder.delete(builder.length-5, builder.length);    // In the entity create a method that executes a query with the string    // If the parameter names are column names then you'd have to use a nativeQuery    // You'd have to look it up in JPA   List<Asset> list = Asset.search(builder.toString());   // put the list in the ModelAndView}
