struts2xml配置向jsp页面带值

Question

client客户表和order订单表是一对多的关系，现在client表中有 @OneToMany
@JoinColumn(name="client_id")
private List orderList;//客户订单
然后我怎么通过struts2把所有order之值带到jsp页面呢

Answer 1

struts2的ajax请求没用过。一直是自己写的工具类
public static String renderText(final T entity) {
try {
getHttpResponse().setContentType("text/plain;charset=UTF-8");
ObjectMapper mapper = new ObjectMapper();
String json = mapper.writeValueAsString(entity);
getHttpResponse().getWriter().write(json);
} catch (final IOException e) {
// LOGGER.error(e.getMessage(), e);
}
return null;
}

这是传对象到前台
传字符串是
public static String renderText(final String text) {
    try {
        getHttpResponse().setContentType("text/plain;charset=UTF-8");
        getHttpResponse().getWriter().write(text);
    } catch (final IOException e) {
        // LOGGER.error(e.getMessage(), e);
    }
    return null;
}
