Question

我正在使用Spring MVC构建带加密的后端服务，我需要在Internet上加密传输所有数据（客户端到服务器和S2C）。

如何在Java Interceptor或Filter上更改正文内容？

public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView mav) throws Exception {
    // I try to change the response body on here.
    // But it seemed can't , I can't read the body out and set new encrypted body back.
}

您可以从modalAndAttribute的客户端 - 服务器拦截任何您想要的内容，这里有一个关于我如何拦截先前呈现给视图的实体的示例，称之为候选资格

@ModelAttribute("candidacy")
public Candidacy bindAbstractOrganizationOnCandidacy(final HttpServletRequest request) throws CandidacyException {
    String discriminator = request.getParameter(CANDIDACY_TYPE);
    Candidacy candidacy = null;
    if (discriminator != null) {
        candidacy = new Candidacy();
        candidacy.setCompany(AbstractCandidacyOrganizationBuilder.buildByDiscriminator(discriminator));
    }
    return candidacy;
}

这就是你需要的吗？
