springcloud项目jar包引用报错

NoSuchMethodError: org.springframework.boot.builder.SpringApplicationBuilder.<init>([Ljava/lang/Object;)V

在springcloud项目中，修改了springcloud的版本信息，由Brixton.SR5修改为Dalston.SR3导致项目启动报错。如下所示：

java.lang.NoSuchMethodError: org.springframework.boot.builder.SpringApplicationBuilder.<init>([Ljava/lang/Object;)V

此错误的原因是springcloud的版本信息与springboot不兼容导致。

 

所以此处给出大家一个spring boot版本和spring cloud版本的匹配关系：

Spring Cloud	Spring Boot
Hoxton	兼容Spring Boot 2.2.x
Greenwich	兼容Spring Boot 2.1.x
Finchley	兼容Spring Boot 2.0.x
Dalston和Edgware	兼容Spring Boot 1.5.x
Camden	兼容Spring Boot 1.4.x
Brixton	兼容Spring Boot 1.3.x
Angel	兼容Spring Boot 1.2.x

 

同时，spingcloud项目再不同的版本中，<dependency>的写法是不同的。

例如在springcloud的Finchley.SR3版本中。eureka-server的依赖是这样的。

<dependency>
   <groupId>org.springframework.cloud</groupId>
   <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>

但是在Brixton.SR5的版本中，eureka-server依赖是这样的

<dependency>
   <groupId>org.springframework.cloud</groupId>
   <artifactId>spring-cloud-starter-eureka-server</artifactId>
</dependency>

如果需要查询不同版本的springcloud包含哪些不同类型依赖。可查询官网
