Spring Boot 例一 实现jsonp接口

1.新建项目(选择quikstart)

2.增加spring boot 依赖

    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-autoconfigure</artifactId>
      <version>1.5..RELEASE</version>
    </dependency>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
      <version>1.5..RELEASE</version>
    </dependency>

3.添加 springboot打包jar 插件依赖

参考 Spring Boot的Maven插件Spring Boot Maven plugin详解

<build>
    <plugins>
      <plugin>
        <artifactId>maven-javadoc-plugin</artifactId>
        <version>2.9.1</version>
        <configuration>
          <encoding>UTF-8</encoding>
          <charset>UTF-8</charset>
          <docencoding>UTF-8</docencoding>
          <skip>true</skip>
        </configuration>
      </plugin>

      <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <executions>
          <execution>
            <goals>
              <goal>repackage</goal>
            </goals>
          </execution>
        </executions>
      </plugin>

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
          <source>1.8</source>
          <target>1.8</target>
          <encoding>UTF-8</encoding>
        </configuration>
      </plugin>
    </plugins>
  </build>

4. 设置启动

application.properties 设置

server.port=9089

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.SpringApplication;
/**
 * Hello world!
 *
 */
@SpringBootApplication
public class App {
    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
}

5. 添加 Contrller层

import com.g2.webtest.model.Person;
import com.g2.webtest.model.PersonReq;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import java.util.HashMap;
import java.util.Map;

@RestController
@RequestMapping("/h5")
public class HomeController {
    private static Map<String, Person> dataSource;
    private static Person anonymous = new Person("未知", 0);

    @RequestMapping(value = "/{code}.jsonp")
    public Person testJsonp(@PathVariable("code") String code) {
        return dataSource.getOrDefault(code, anonymous);
    }

    @RequestMapping(value = "/person", consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType
            .APPLICATION_JSON_VALUE)
    @ResponseBody
    public Person testJsonp2(@RequestBody PersonReq req) {
        return dataSource.getOrDefault(req.getCode(), anonymous);
    }

    static {
        dataSource = new HashMap<>();
        dataSource.put("1001", new Person("张三", 15));
        dataSource.put("1002", new Person("李四", 18));
    }
}

public class Person {
    private String name;
    private int age;

    public Person(){
        this("",0);
    }
    public Person(String name,int age){
        this.name=name;
        this.age=age;
    }
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
}

6.设置jsonp的配置

import com.g2.webtest.controller.h5.HomeController;

import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.servlet.mvc.method.annotation.AbstractJsonpResponseBodyAdvice;

@ControllerAdvice(basePackageClasses = {HomeController.class})
public class JSONPConfiguration extends AbstractJsonpResponseBodyAdvice {
    public JSONPConfiguration(){
        super("callback","jsonp");
    }
}

7.测试

http://127.0.0.1:9089/h5/1001.jsonp?callback=myfun

myfun({"name":"张三","age":15});
