Question

在我的消息属性中，我定义了许多文本，它们都可以工作...但是我不知道为什么。

这是我关注的模板div：

<div>
                <label for="datePlanted">
                    <span th:text="#{seedstarter.datePlanted}">Date planted</span>
                    (<span th:text="#{date.format}">YYYY/MM/DD</span>)
                </label>
                <input type="text" th:field="*{datePlanted}" th:errorclass="fieldError"/>
            </div>

但是我的邮件属性中没有date.format条目！这是怎么回事？

我唯一的线索是在我的WebConfig中：

@Configuration
@EnableWebMvc
@ComponentScan
public class SpringWebConfig
        extends WebMvcConfigurerAdapter implements ApplicationContextAware {
.
.
.
@Override
    public void addFormatters(final FormatterRegistry registry) {
        super.addFormatters(registry);
        registry.addFormatter(varietyFormatter());
        registry.addFormatter(dateFormatter());
    }

    @Bean
    public VarietyFormatter varietyFormatter() {
        return new VarietyFormatter();
    }

    @Bean
    public DateFormatter dateFormatter() {
        return new DateFormatter();
    }

Messages.properties

title.application=Spring Thyme Seed-Starter Manager
title.list=Seed Starter List
title.new=Add new Seed Starter

date.format=MM/dd/yyyy
bool.true=yes
bool.false=no

seedstarter.data=Seed Starter data
seedstarter.create=Add Seed Starter
seedstarter.row.add=Add row
seedstarter.row.remove=Remove row

seedstarter.datePlanted=Date planted
seedstarter.covered=Covered
seedstarter.type=Type
seedstarter.features=Features
seedstarter.rows=Rows

seedstarter.type.WOOD=Wood
seedstarter.type.PLASTIC=Plastic

seedstarter.feature.SEEDSTARTER_SPECIFIC_SUBSTRATE=Seed starter-specific substrate
seedstarter.feature.FERTILIZER=Fertilizer used
seedstarter.feature.PH_CORRECTOR=PH Corrector used

seedstarter.rows.head.rownum=Row
seedstarter.rows.head.variety=Variety
seedstarter.rows.head.seedsPerCell=Seeds per cell

typeMismatch.datePlanted=Date has an incorrect format (see pattern)
typeMismatch.seedsPerCell=Seeds per cell must be an integer number

DateFormatter.java 该文件也在项目中。它包含

最终字符串格式= this.messageSource.getMessage（“ date.format”， null，区域设置）；

我对MessageSource知之甚少，除了它的一个Spring库，它有3种返回字符串并采用“字符串代码”，默认消息，语言环境或MessageSourceResolvable的方法。我对这是如何工作的细节感到很困惑，但我看到DateFormatter会像这样处理视图...

DateFormatter.java

 public class DateFormatter implements Formatter<Date> {

    @Autowired
    private MessageSource messageSource;


    public DateFormatter() {
        super();
    }

    public Date parse(final String text, final Locale locale) throws ParseException {
        final SimpleDateFormat dateFormat = createDateFormat(locale);
        return dateFormat.parse(text);
    }

    public String print(final Date object, final Locale locale) {
        final SimpleDateFormat dateFormat = createDateFormat(locale);
        return dateFormat.format(object);
    }

    private SimpleDateFormat createDateFormat(final Locale locale) {
        final String format = this.messageSource.getMessage("date.format", null, locale);
        final SimpleDateFormat dateFormat = new SimpleDateFormat(format);
        dateFormat.setLenient(false);
        return dateFormat;
    }

}

Thymeleaf th：text =“＃{date.format}”有效，但在messages.properties中没有任何条目
