org.springframework.http.converter.HttpMessageNotWritableException: No converter for [class com.citicpress.contract.dto.common.ResponseParam] with preset Content-Type 'application/vnd.ms-excel'

这个异常通常发生在Spring框架中,表示在处理响应时找不到合适的转换器来将响应对象转换为预设的Content-Type类型(这里是'application/vnd.ms-excel')。这意味着需要配置一个合适的转换器来处理这种类型的响应。
要解决这个问题,你可以尝试以下几种方法:
1. 确保在你的项目中添加了合适的依赖。对于Excel类型的响应,你可能需要添加类似于Apache POI或其他Excel处理库的依赖。
2. 在你的Spring配置文件中配置适当的转换器。你可以使用`<mvc:message-converters>`标签来配置转换器,确保包含适当的转换器来处理Excel类型的响应。
3. 确保在你的控制器方法中使用了合适的注解来指定返回的Content-Type。你可以使用`@Produces`注解来指定返回的媒体类型为'application/vnd.ms-excel'。
4. 如果你正在使用自定义的转换器,确保它正确地实现了`HttpMessageConverter`接口,并且能够处理Excel类型的响应。
这些是一些常见的解决方法,但具体的解决方案可能因你的项目配置和需求而有所不同。希望能对你有所帮助!

There is no getter for property named 'categryId' in 'class com.sky.dto.SetmealPageQueryDTO'
从给出的引用中可以看出,问题出现在Mybatis的映射文件中。报错信息"There is no getter for property named 'categoryId' in 'class com.sky.dto.SetmealPageQueryDTO'"表明在'com.sky.dto.SetmealPageQueryDTO'类中找不到名为'categoryId'的属性的getter方法。这意味着在映射文件中使用了错误的字段名'#{categoryId}'。正确的字段应该是'#{categryId}',即字段名应为'categryId'。所以需要将映射文件中的'#{categoryId}'修改为'#{categryId}'即可解决此问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

There is no getter for property named 'updateTime' in 'class com.sky.dto.EmployeeDTO'
It seems that you are encountering an issue with the 'updateTime' property in the 'EmployeeDTO' class. The error message states that there is no getter method defined for this property. In order to access the value of the 'updateTime' property, you need to create a getter method in the 'EmployeeDTO' class.
Here is an example of how you can add a getter method for the 'updateTime' property in Java:
```java
public class EmployeeDTO {
private Date updateTime;
// Getter method for 'updateTime'
public Date getUpdateTime() {
return updateTime;
}
// Setter method for 'updateTime' (if needed)
public void setUpdateTime(Date updateTime) {
this.updateTime = updateTime;
}
// Other properties and methods
}
```
By adding a getter method like the one shown above, you should be able to access the value of the 'updateTime' property in your code.
