在Spring Boot的RestController中找不到404

Question

我有一个带有pom.xml的Spring Boot项目，像这样<groupId>com.project</groupId>    <artifactId>prj</artifactId>    <version>0.0.1-SNAPSHOT</version>    <packaging>jar</packaging>    <name>prj</name>    <description>Demo project for Spring Boot</description>    <parent>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-parent</artifactId>        <version>2.0.3.RELEASE</version>        <relativePath/> <!-- lookup parent from repository -->    </parent>    <properties>        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>        <java.version>1.8</java.version>    </properties>    <dependencies>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-actuator</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-data-jpa</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-devtools</artifactId>            <scope>runtime</scope>        </dependency>        <dependency>            <groupId>com.h2database</groupId>            <artifactId>h2</artifactId>            <scope>runtime</scope>        </dependency>当我尝试通过使用PostMan调用post方法来保存用户时，它给了我404 not found错误。{    "timestamp": "2018-06-23T06:47:14.086+0000",    "status": 404,    "error": "Not Found",    "message": "No message available",    "path": "/prj/register/new"}我正在使用JPARepository执行数据库操作。

Answer 1

/prj不是您的控制器的一部分。使用没有POST请求的请求（即/register/new），或将其添加到控制器的映射中：

@RestController("/prj/register")

public class RegisterController {

    // rest of the code (no pun intended)
