更改Webflux运行Jetty而不是Netty后获取异常

时间：2018-05-11 18:42:07

标签： spring-boot jetty netty spring-webflux

我想在Jetty而不是Netty上运行我的Spring Boot Webflux应用程序，我找到了on this link我可以做的事情：

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-webflux</artifactId>
     <exclusions>
        <exclusion>
            <artifactId>spring-boot-starter-reactor-netty</artifactId>
            <groupId>org.springframework.boot</groupId>
        </exclusion>
    </exclusions>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jetty</artifactId>
</dependency>

当我尝试时，我的应用程序中出现异常：

....

排除netty后，我仍然可以看到我的Redis异步调用中存在netty依赖关系

所以我的问题是在Jetty上运行Webflux还没有得到完全支持吗？或者我的dependecy版本有问题，我也需要做一些关于redis的事情吗？

1 个答案:

答案 0 :(得分：0)

首先，该文件中可能存在拼写错误。 spring-boot-starter-reactor-netty工件应从spring-boot-starter-webflux排除，而不是从spring-security-webflux排除：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-webflux</artifactId>
    <exclusions>
        <exclusion>
            <artifactId>spring-boot-starter-reactor-netty</artifactId>
            <groupId>org.springframework.boot</groupId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jetty</artifactId>
</dependency>

另一件事是，myService bean直接要求一个HttpClient bean。 myService bean听起来像是你的课程。您应该检查是否在任何字段中注入HttpClient。
