1 基本信息

1.1 来源:

这个类是 下面的依赖中的

依赖关系

+- org.springframework.ai:spring-ai-mcp:jar:1.0.0-SNAPSHOT:compile
[INFO]    |  +- io.modelcontextprotocol.sdk:mcp:jar:0.10.0:compile

可以看出这个是官方的.

1.2 内容

这个类主要是对mcp中的数据结构进行定义的类,包含请求 ,响应以及工具调用的参数说明.

简单来说uiu是rpcschema和inputschema

2  具体内容举例

例如:CallToolResult

public static record CallToolResult(List<Content> content, Boolean isError) {
    public CallToolResult(String content, Boolean isError) {
        this(List.of(new TextContent(content)), isError);
    }

    public CallToolResult(@JsonProperty("content") List<Content> content, @JsonProperty("isError") Boolean isError) {
        this.content = content;
        this.isError = isError;
    }

    public static Builder builder() {
        return new Builder();
    }

    @JsonProperty("content")
    public List<Content> content() {
        return this.content;
    }

    @JsonProperty("isError")
    public Boolean isError() {
        return this.isError;
    }

    public static class Builder {
        private List<Content> content = new ArrayList();
        private Boolean isError;

        public Builder() {
        }

        public Builder content(List<Content> content) {
            Assert.notNull(content, "content must not be null");
            this.content = content;
            return this;
        }

        public Builder textContent(List<String> textContent) {
            Assert.notNull(textContent, "textContent must not be null");
            Stream var10000 = textContent.stream().map(TextContent::new);
            List var10001 = this.content;
            Objects.requireNonNull(var10001);
            var10000.forEach(var10001::add);
            return this;
        }

        public Builder addContent(Content contentItem) {
            Assert.notNull(contentItem, "contentItem must not be null");
            if (this.content == null) {
                this.content = new ArrayList();
            }

            this.content.add(contentItem);
            return this;
        }

        public Builder addTextContent(String text) {
            Assert.notNull(text, "text must not be null");
            return this.addContent(new TextContent(text));
        }

        public Builder isError(Boolean isError) {
            Assert.notNull(isError, "isError must not be null");
            this.isError = isError;
            return this;
        }

        public CallToolResult build() {
            return new CallToolResult(this.content, this.isError);
        }
    }
}

这个类是call工具结果的类,这种builder初始化的类在框架中经常出现,就是一个静态builder方法,然后里面初始化内部类Builder,拿到这个builder之后,再调用它的build方法就完成了真正的初始化

比如:

 CallToolResult.Builder builder = CallToolResult.builder();

然后设置内容

  builder.content

 最后调用build方法构建返回对象

 CallToolResult result = builder.build();
