Question

spring boot主类

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@SpringBootApplication
@Configuration
@ComponentScan(basePackages = { "com.example.demo" })
@EnableAutoConfiguration
public class CrudApplication {

    public static void main(String[] args) {
        SpringApplication.run(CrudApplication.class, args);
    }

}

带有cxf批注的REST API的类不起作用

@Path("/main")
public class ControllerClass {
       @GET
       @Path("/cxf")
       public String addcsf(@RequestParam String name) {

            Emp emp = new Emp();
            emp.setName(name);


            empDao.save(emp);

            String ret = "CXFFFFFFFF, user name = " + name;

            return ret;

        }

}

但无需cxf即可工作

@Controller
public class ControllerClass {
    @Autowired
    EmpDao empDao;

       @GetMapping(path = "/add")
        @ResponseBody
        public String addUser(@RequestParam String name) {

            Emp emp = new Emp();
            emp.setName(name);


            empDao.save(emp);

            String ret = "User account has been added, user name = " + name;

            return ret;

        }
}

添加pom.xml 我在其中添加了apache cxf

能请你告诉我我在这件事中缺少什么吗添加cxf时出现以下错误白标错误页面此应用程序没有针对/ error的显式映射，因此您将其视为后备。

2019年3月15日星期五16:10:05 发生意外错误（类型=未找到，状态= 404）。无讯息这是我的application.propertiesfile

cxf.path=/services
cxf.jaxrs.client.headers.accept=text/plain
cxf.jaxrs.client.classes-scan-packages=com.example.demo
# MySQL jdbc connection url.
spring.datasource.url=jdbc:mysql://localhost:3306/restapi

Answer 1

在下面的示例中为我工作。

测试网址http://localhost:8080/services/main/cxf

application.properties

cxf.path=/services
cxf.jaxrs.client.headers.accept=text/plain
cxf.jaxrs.client.classes-scan-packages=com.example.cxfboot

控制器类

package com.example.cxfboot;

import javax.ws.rs.GET;
import javax.ws.rs.Path;

import org.springframework.web.bind.annotation.RequestParam;

@Path("/main")
public class ControllerClass {
    @GET
    @Path("/cxf")
    public String addcsf(@RequestParam String name) {

        System.out.println("Ghanta");

        return "BC";

    }

}

配置类。

import org.apache.cxf.Bus;
import org.apache.cxf.endpoint.Server;
import org.apache.cxf.jaxrs.JAXRSServerFactoryBean;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;

@SpringBootApplication
public class CxfBootApplication {

    public static void main(String[] args) {
        SpringApplication.run(CxfBootApplication.class, args);
    }

    @Autowired
    private Bus bus;

    @Bean
    public Server rsServer() {
        JAXRSServerFactoryBean endpoint = new JAXRSServerFactoryBean();
        endpoint.setBus(bus);
        endpoint.setServiceBeans(Arrays.<Object>asList(new ControllerClass()));
        endpoint.setAddress("/");
        return endpoint.create();
    }
}

和pom.xml

带有Spring Boot的apache cxf无法正常工作，但带有其他注释的spring boot可以正常工作吗？
