spring boot 2.1.x整合jersey遇到的坑

由于最近的开发需要用到这个框架，所以打算重新学习下，但是spring boot的版本升级了，导致了依赖方面一些问题，应用老是起不来，没想到这个还是spring boot的bug...这里记录一下:

首先来看一下相关的依赖:

<dependencies>
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter</artifactId>
    		</dependency>
    
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-test</artifactId>
    			<scope>test</scope>
    		</dependency>
    
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-actuator</artifactId>
    
    		</dependency>
    
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-jersey</artifactId>
    		</dependency>
    </dependencies>

必须要强调一下:1.不要导入spring boot 的web组件！2.不要忘记添加actuator组件。

不知道何种原因，其他的一些文章上边都会导入web相关的依赖，结果还能得到正确的结果...

然后是配置类代码:

@Component
    @ApplicationPath("/rest")
    public class JerseyConfig extends ResourceConfig {
    
        public JerseyConfig() {
            register(ControllerTest.class);
        }
    
    }

最后是控制类部分的代码:

@Component
    @Path("/test")
    public class ControllerTest {
        @GET()
        @Path("jsonTest")
        @Produces(MediaType.APPLICATION_JSON)
        public Object jsonMessage() {
            Map<String, String> tmp = new HashMap<>();
            tmp.put("info", "hi");
            return tmp;
        }
    
        @GET
        @Path("{id}")
        @Produces(MediaType.TEXT_PLAIN)
        public Object testMessage(@PathParam("id") Integer id, @QueryParam("name") String name) {
            StringBuilder sb = new StringBuilder();
            sb.append("this is id:").append(id).append("this is name:").append(name);
            return sb.toString();
        }
    
        @POST
        @Path("/cat")
        @Produces(MediaType.APPLICATION_JSON)
        @Consumes(MediaType.APPLICATION_JSON)
        public Object catMessage(Cat cat) {
            return cat;
        }
    }

实验的结果:

对于jesery的整合完毕。
