請求參數(shù)傳json對象，后端采用（pojo）接收的前提條件：

1.pom.xml文件加入坐標(biāo)依賴：jackson-databind
2.Spring Boot 的啟動類加注解：@EnableWebMvc
3.Spring Boot 的Controller接受參數(shù)采用：@RequestBody
4.postman入?yún)⒉捎胘son格式

1.pom.xml文件加入坐標(biāo)：

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.9.8</version>
</dependency>

2.Spring Boot 啟動類：加注解：@EnableWebMvc

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.openfeign.EnableFeignClients;
import org.springframework.context.annotation.Bean;
import org.springframework.http.client.ClientHttpRequestFactory;
import org.springframework.http.client.SimpleClientHttpRequestFactory;
import org.springframework.web.client.RestTemplate;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

@SpringBootApplication
@EnableWebMvc
@EnableFeignClients(basePackages = {
        "com.itheima.platform.common.feign.services.home",
        "com.itheima.bcg.service.fegin",
        "com.itheima.platform.common.feign.services.paperTask",
        "com.itheima.platform.common.feign.services.problem",
        "com.itheima.platform.common.feign.services.auth",
		"com.itheima.platform.common.feign.services.bpmn"})
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

	@Bean
	public RestTemplate restTemplate() {
		//復(fù)雜構(gòu)造函數(shù)的使用
		SimpleClientHttpRequestFactory requestFactory = new SimpleClientHttpRequestFactory();
		requestFactory.setConnectTimeout(300000);// 設(shè)置超時
		requestFactory.setReadTimeout(300000);
		RestTemplate restTemplate = new RestTemplate();
		restTemplate.setRequestFactory(requestFactory);
		return restTemplate;
	}

	@Bean
	public ClientHttpRequestFactory simpleClientHttpRequestFactory() {
		SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory();
		factory.setConnectTimeout(150000);
		factory.setReadTimeout(50000);
		return factory;
	}
}

POJO類：

import lombok.Data;

@Data
public class Config {
    private int seqId;
    private int sortId;
    private String interfaceType;
    private String dicNameFirst;
    private int dicValueFirst;
    private String dicNameSecond;
    private int dicValueSecond;
    private String dicType;
    private String isEnable;
}

3.Controller接受參數(shù)采用：@RequestBody
Controller類：
備注：為了便于測試：Controller類只寫了一個接口（實際開發(fā)可不要這樣寫噢）

	/*
     * 請求參數(shù)傳json對象（POJO）
     *
     */
    @PostMapping(value = "/addTest")
    @AuthInterceptor("mg:get:addTest")
    public Result addTest(@RequestBody Config config) {
        try {
            return xxxListService.addTest(config);
        } catch (Exception e) {
            log.error("Controller addTest is error===:" + e.getMessage(), e);
            return Result.failure("測試成功");
        }
    }
    

Service類：

	Result addTest(Config config);

ServiceImpl類：

 	@Override
    public Result addTest(Config config) {
        List<Map<String, Object>> res = new ArrayList<>();
        String interfaceType = config.getInterfaceType();
        if(interfaceType.equals("add")){
            xxxListMapper.addTest(config);
        }
        else if(interfaceType.equals("del")){
            xxxListMapper.delTest(config);
        }
        else if(interfaceType.equals("modify")){
            xxxListMapper.modifyTest(config);
        }
        else if(interfaceType.equals("sel")){
            res = xxxListMapper.selTest(config);
        }
        return Result.success().result(res);
    }
    

Mapper類：

	
	//新增
    void addTest(Config config);
    //刪除
    void delTest(Config config);
    //修改
    void modifyTest(Config config);
    //查詢
    List<Map<String, Object>> selTest(Config config);
    

Mapper.xml類

	<!-- 新增 -->
    <insert id="addTest">
        INSERT IGNORE INTO xxx_other_list_dic
        (dicNameFirst,dicValueFirst,dicNameSecond,dicValueSecond,dicType,isEnable)
        VALUES
        (#{dicNameFirst},#{dicValueFirst},#{dicNameSecond},#{dicValueSecond},#{dicType},#{isEnable})
    </insert>
    <!-- 刪除 -->
    <select id="delTest">
        delete
        FROM xxx_other_list_dic where
        <if test = "null != seqId and '' != seqId">
            seqId = #{seqId}
        </if>
    </select>
    <!-- 修改 -->
    <update id="modifyTest">
        update xxx_other_list_dic
        <set>
            <if test = "null != sortId and '' != sortId">
                sortId = #{sortId},
            </if>
            <if test = "null != isEnable and '' != isEnable">

            </if>
        </set>
        where
        <if test = "null != seqId and '' != seqId">
            seqId = #{seqId}
        </if>
    </update>
    <!-- 查詢 -->
    <select id="selTest" resultType="map">
        SELECT *
        FROM xxx_other_list_dic where 1 = 1
        <if test="null != dicNameFirst and '' != dicNameFirst">
            and dicNameFirst = #{dicNameFirst}
        </if>
        <if test="null != dicValueFirst and '' != dicValueFirst">
            and dicValueFirst = #{dicValueFirst}
        </if>
        <if test="null != dicNameSecond and '' != dicNameSecond">
            and dicNameSecond = #{dicNameSecond}
        </if>
        <if test="null != dicValueSecond and '' != dicValueSecond">
            and dicValueSecond = #{dicValueSecond}
        </if>
        <if test="null != dicType and '' != dicType">
            and dicType = #{dicType}
        </if>
        <if test="null != isEnable and '' != isEnable">
            and isEnable = #{isEnable}
        </if>
        order by sortId
    </select>
