Dependency mediation - this determines what version of an artifact will be chosen when multiple versions are encountered as dependencies. Maven picks the "nearest definition". That is, it uses the version of the closest dependency to your project in the tree of dependencies. You can always guarantee a version by declaring it explicitly in your project's POM. Note that if two dependency versions are at the same depth in the dependency tree, the first declaration wins.

"nearest definition" means that the version used will be the closest one to your project in the tree of dependencies. Consider this tree of dependencies:

A
├── B
│ └── C
│ └── D 2.0
└── E
└── D 1.0

In text, dependencies for A, B, and C are defined as A -> B -> C -> D 2.0 and A -> E -> D 1.0, then D 1.0 will be used when building A because the path from A to D through E is shorter.

有方法，但是不建议这样搞


@RestControllerAdvice
public class RespVoAdvice implements ResponseBodyAdvice<Object> {
@Override
public Object beforeBodyWrite(Object body, MethodParameter returnType, MediaType selectedContentType, Class<? extends HttpMessageConverter<?>> selectedConverterType, ServerHttpRequest request, ServerHttpResponse response) {

if (body == null) {
return "{}"
}
return body;
}
}

@em70 我勒个去，这都能扯上

@gamexg 绝对是故意的，亏 145 ，邻居的钱可以忽略，就亏了进价的 80 和找出去的 65

我现在就是两个路由器，第一个是有线的，设置路由器 ip 地址 192.168.1.1, 网关地址 192.168.1.1 ，子网掩码 255.255.255.0 ，第二个是无线路由器，设置 ip 地址为 192.168.2.1, 网关地址 192.168.2.1, 子网掩码 255.255.255.0

朋友好求，知心难得，特别是能一直陪着走下去的。
