Spring 以编程方式解析ELEAF模板

我正在尝试使用Thymeleaf模板呈现XML/JSON。我不想使用模板名称渲染视图，只想解析模板，如下所示。问题是我得到的只是模板名，而不是它的内容

设置：

@Bean
SpringResourceTemplateResolver xmlTemplateResolver(ApplicationContext appCtx) {
    SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();

    templateResolver.setApplicationContext(appCtx);
    templateResolver.setPrefix("classpath:/templates/");
    templateResolver.setSuffix(".xml");
    templateResolver.setTemplateMode(XML);
    templateResolver.setCharacterEncoding(UTF_8.name());
    templateResolver.setCacheable(false);

    return templateResolver;
}

@Bean
SpringTemplateEngine templateEngine(ApplicationContext appCtx) {
    SpringTemplateEngine templateEngine = new SpringTemplateEngine();
    templateEngine.addTemplateResolver(xmlTemplateResolver(appCtx));

    return templateEngine;
}

<?xml version="1.0" encoding="UTF-8"?>
<breakfast_menu>
    <food>
        <name>${item['name']}</name>
        <price>${item['price']}</price>
        <description>${item['description']}</description>
        <calories>${item['calories']}</calories>
    </food>
</breakfast_menu>

@Autowired
SpringTemplateEngine templateEngine;

someMethod() {
    Context context = new Context();
    context.setVariable("item", item);
    item.put("name", "Waffle");
    String content = templateEngine.process("breakfast-menu", context);

    // content == "breakfast-menu". WTH?
}

模板（src/main/resources/templates/早餐菜单.xml）：

@Bean
SpringResourceTemplateResolver xmlTemplateResolver(ApplicationContext appCtx) {
    SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();

    templateResolver.setApplicationContext(appCtx);
    templateResolver.setPrefix("classpath:/templates/");
    templateResolver.setSuffix(".xml");
    templateResolver.setTemplateMode(XML);
    templateResolver.setCharacterEncoding(UTF_8.name());
    templateResolver.setCacheable(false);

    return templateResolver;
}

@Bean
SpringTemplateEngine templateEngine(ApplicationContext appCtx) {
    SpringTemplateEngine templateEngine = new SpringTemplateEngine();
    templateEngine.addTemplateResolver(xmlTemplateResolver(appCtx));

    return templateEngine;
}

<?xml version="1.0" encoding="UTF-8"?>
<breakfast_menu>
    <food>
        <name>${item['name']}</name>
        <price>${item['price']}</price>
        <description>${item['description']}</description>
        <calories>${item['calories']}</calories>
    </food>
</breakfast_menu>

@Autowired
SpringTemplateEngine templateEngine;

someMethod() {
    Context context = new Context();
    context.setVariable("item", item);
    item.put("name", "Waffle");
    String content = templateEngine.process("breakfast-menu", context);

    // content == "breakfast-menu". WTH?
}

使用Thymeleaf 3.0.0.BETA01.

我在Thymeleaf的帮助下解决了这个问题。由于我不知道的原因，

templateEngine.addTemplateResolver

不工作，但

templateEngine.settTemplateResolver

工作。XML和JSON输出的模板如下所示：
