set to application/json
As an AI language model, I don't have access to the context of the situation where this error message was displayed. However, this error message generally indicates that the server received a request that was expected to contain JSON data, but the request did not have the correct Content-Type header set to indicate that it was sending JSON data. The server cannot process the request without this information, so it does not attempt to load the JSON data. The requester should ensure that the request's Content-Type header is set to application/json when sending JSON data.

Did not attempt to load JSON data because the request Content-Type was not 'application/json'.
这个错误信息通常出现在前端(浏览器端)向后端(服务器端)请求数据时,请求头的 Content-Type 不是 'application/json' 时出现。在这种情况下,浏览器会认为返回的数据不是 JSON 格式的,因此会拒绝解析。
要解决这个问题,可以在前端代码中设置请求头的 Content-Type 为 'application/json',例如:
```
const xhr = new XMLHttpRequest();
xhr.open('POST', '/api/data');
xhr.setRequestHeader('Content-Type', 'application/json');
xhr.onreadystatechange = function() {
if (xhr.readyState === 4 && xhr.status === 200) {
const data = JSON.parse(xhr.responseText);
// 处理返回的数据
}
};
const requestData = { /* 请求数据 */ };
xhr.send(JSON.stringify(requestData));
```
在这个例子中,我们使用 XMLHttpRequest 对象向服务器端发送 POST 请求,并设置请求头的 Content-Type 为 'application/json'。在发送请求时,我们还将请求数据使用 JSON.stringify() 方法转换为 JSON 格式的字符串。在获取到响应数据后,我们再使用 JSON.parse() 方法将响应数据转换回 JavaScript 对象。
@conditionalonmissingbean did not specify a bean using type, name or annotation and the attempt to deduce the bean's type failed
这个错误提示意味着在使用@conditionalonmissingbean注解时,没有指定bean的类型、名称或注解,而且尝试推断bean的类型也失败了。可能需要检查注解的使用方式或者bean的定义是否正确。
